1–Introduction Power and Cooling Module (PCM)

Each blade is capable of simultaneously driving all six fans in both PCMs. Generally, only one blade controls both fans, running them at a normal speed. However, if the system detects a higher-than-expected temperature on either side of the blade, it forces the fans to run at full speed. After the temperature is back to normal, the fans resume running at their normal speed.

Table 1-1 shows the internal temperature limits set to trigger events or server

message block (SMB) alerts.

The following describes the fan speed and temperature parameters listed in

 High Fan Speed Temperature—When a sensor detects a temperature that

exceeds this value, the fans run at their maximum RPM speed. The system logs the event and the system fault LED blinks five times every two seconds.

 Low Fan Speed Recovery Temperature—When the fans are running at

their maximum RPM and all sensors report values less than this value, the fan speed resets to normal.

 Critical Temperature—When a sensor detects a temperature that exceeds

this value, the system powers down the blade. When this happens, the CPUs enter sleep state 5. The system sets the peripheral component interface (PCI) power state of capable devices to D3, and then turns off the power supplies not essential to wake up the CPUs. When the temperature goes below the Recovery Temperature value, the sensor that reported the over-temperature value generates an SMB_ALERT.

 Recovery Temperature—Value at which a sensor generates an

SMB_ALERT to wake up the CPU and cause the blade to reboot.

3. When the POST is complete, the power LED is on and the heartbeat LED flashes once per second.

1–Introduction

iSR6200 Router Blades

Reset and Select Boot Image

You can reset the router using either the primary or secondary boot image:

 Primary Image—To reset the router and select the primary boot image, use

a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes once, and then release the button. The router boots from the primary boot image. The boot time is less than one minute.

 Secondary Image—To reset the router and select the secondary boot

image, use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes twice, and then release the button. The heartbeat LED flashes twice. The router boots from secondary boot image. The boot time is less than one minute.

Reset IP Address

To reset the router and restore the maintenance port IP address to the default (10.0.0.1), use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes six times, and then release the button. The router boots and sets the maintenance port to IP address 10.0.0.1. The boot time is less than one minute.

The IP address set by this method is not persistent; to make the change persistent, use the CLI or SANsurfer Router Manager to set the IP address. For more information, see the iSR6200 Router Manager User’s Guide and the iSR6200 CLI User’s Guide.

Enable DHCP

To reset the router and configure the maintenance port to use dynamic host configuration protocol (DHCP) to acquire its IP address, use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes seven times, and then release the button. The router boots and configures the maintenance port for DHCP. The boot time is less than one minute.

Enabling DHCP by this method is not persistent; to make the change persistent, use the CLI or SANsurfer Router Manager to enable DHCP. For details, see the see the iSR6200 Router Manager User’s Guide and the iSR6200 CLI User’s Guide.

Restore Factory Defaults

To reset the router and restore it to the factory default configuration, use a pointed, nonmetallic tool to press the maintenance button and hold it until the heartbeat LED flashes 20 times, and then release the button. The router boots and is restored to the factory defaults. The boot time is less than one minute.

The router does the following when restored to the factory defaults:

 Clears all router log entries  Resets all passwords  Resets the maintenance port IP address to 10.0.0.1  Disables the iSCSI ports and sets the IP address to 0.0.0.0  Erases all presentations  Erases all discovered initiators and targets

Fibre Channel Port LEDs

The iSR6200 router has two Fibre Channel ports. The ports are labeled FC1 and FC2, as shown in Figure 1-10.

Fibre Channel Transceivers

Each port is served by an SFP optical transceiver and is capable of 2, 4, or 8Gbps transmission. SFPs are hot-pluggable. User ports can self-discover both the port type and transmission speed when connected to public devices or switches.

ISR651101-00 E 1-11

1–Introduction

Activity Link Status

iSR6200 Router Blades

The iSR6200 router supports SFP optical transceivers for the Fibre Channel ports. A transceiver converts electrical signals to and from optical laser signals to transmit and receive data. Duplex fiber optic cables plug into the transceivers, which then connect to the devices. For example, a 2Gbps or 4Gbps Fibre Channel port can transmit at 2Gbps or 4Gbps; however, the transceiver must also be capable of delivering these rates.

The SFP transceivers are hot pluggable. You can remove or install a transceiver while the router is operating without harming the router or the transceiver. However, this interrupts communication with the connected device. For details about installing and removing SFP optical transceivers, see “Installing the

Transceivers” on page 3-6.

Gigabit Ethernet Port LEDs

The gigabit Ethernet (GbE) ports shown in Figure 1-11 are RJ45 connectors that provide connection to an Ethernet SAN through a 100 or 1000 Base-T Ethernet cable. The ports are labeled GE1 and GE2. Each of these ports supports connections that run the iSCSI high-level TCP protocol.

2 Planning

This chapter describes how to plan for the iSR6200 router. The following sections describe the devices and services you need to consider when planning to use the iSR6200 router:

 “Devices” on page 2-1  “Device Access” on page 2-1  “Fibre Channel Switches Required for VPGroups” on page 2-2  “Fibre Channel Performance” on page 2-2  “iSCSI Performance” on page 2-3  “Performance Tuning” on page 2-4  “High Availability” on page 2-7  “Management” on page 2-7  “Recovery” on page 2-7  “Services” on page 2-8  “Security” on page 2-8

Devices

When planning router use, consider the number of devices and the anticipated demand. This determines the number of ports required and, in turn, the number of routers.

The router uses SFP transceivers in the 8Gbps Fibre Channel (FC) ports, but some Fibre Channel devices may not use the same transceivers. Consider whether the Fibre Channel device you want to connect the router to uses SFP or gigabit interface converters (GBIC) transceivers, and choose fibre optic cables accordingly. Use LC-type cable connectors for SFP transceivers and SC-type cable connectors for GBIC transceivers. Also consider the transmission speed compatibility of your devices, adapters, switches, and SFPs.

Device Access

Consider device access needs within the Fibre Channel and iSCSI SANs. Controlling access to Fibre Channel device LUNs requires mapping Fibre Channel device LUNs to specific iSCSI initiators. You may map LUNs to more than one initiator. Giving multiple initiators access to a LUN requires access management.

ISR651101-00 E 2-1

2–Planning Fibre Channel Switches Required for VPGroups

Fibre Channel

The Fibre Channel ports automatically discover all Fibre Channel target devices, whether connected directly (loop) or by fabric (switch).

iSCSI

The iSCSI ports automatically present targets discovered on the Fibre Channel ports. If the Fibre Channel target’s LUN 0 is a controller LUN, it becomes accessible (mapped) to all iSCSI initiators. All data LUNs are inaccessible until mapped. The exception is if LUN 0 is a controller LUN, it is mapped automatically to allow for management of the Fibre Channel target controller.

When an iSCSI initiator logs on, the router records the initiator’s iSCSI name and IP address. The management interface—CLI and SANsurfer Router Manager—uses the initiator information to simplify the mapping process.

Fibre Channel Switches Required for VPGroups

iSR6200 uses QLogic Host Bus Adapter technology and is compatible with all Fibre Channel switches from Brocade, Cisco, McData, and QLogic. If you want to use more than one VPGroup, you must use Fibre Channel switches.

Fibre Channel Performance

The iSR6200 router supports Fibre Channel service at transmission rates of 2, 4, or 8 Gbps with a maximum frame size of 2,148 bytes. Related performance characteristics include the following:

 Distance  Bandwidth  Latency

Distance

Consider the physical distance between Fibre Channel devices. Choose SFP transceivers that are compatible with the cable type and distance.

Each Fibre Channel port is supported by a data buffer with a three-credit capacity; that is, three maximum-sized frames. For fibre optic cables, this enables full bandwidth over approximately 2.5 kilometers at 2Gbps (1.2 credits/Km).

Beyond these distances, however, the connection loses some efficiency because the transmitting port must wait for an acknowledgement before sending the next frame.

2-2 ISR651101-00 E

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a specific transmission rate. A 2Gbps Fibre Channel port can transmit or receive at nominal rates of 2Gbps, depending on the device to which it is connected. This corresponds to actual bandwidth value of 212MB.

Latency

Latency is a measure of how fast a transaction travels through the router.

iSCSI Performance

The iSR6200 router supports Ethernet service at transmission rates of 1000Mbps, 100Mbps, or 10Mbps with an MTU size of 1500 or 9000 (jumbo frames).

NOTE:

An MTU size greater than 1500 should only be used when the router is connected to a 1000Mbps Ethernet network.

2–Planning

iSCSI Performance

Related performance characteristics include the following:

 Distance  Bandwidth  Latency

Distance

Consider the physical distance between routers.This is usually measured in round-trip delay. Round-trip delays range anywhere from less than 1 millisecond to as great as 250 milliseconds.

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a specific transmission rate. WAN data rates range from 1.5 megabits per second (T1) to greater than 600 megabits per second (OC-12).

Latency

Latency is a measure of how fast a transaction travels through the router and LAN or WAN.

ISR651101-00 E 2-3

2–Planning Performance Tuning

Performance Tuning

Proper configuration maximizes the router’s performance. Knowing the round-trip delay (distance between the router and iSCSI initiators) and WAN effective data rate (connection type) allows you to tune the router for optimal performance. The following tables provide TCP Window Size settings for specific WAN environments. The TCP Window Size is configured as two parameters: Window Size and Scaling Factor. See the iSR6200 Router Manager User’s Guide and the iSR6200 CLI User’s Guide for configuring the TCP window size.

High Availability

A dual-blade iSR6200 router supports high availability, which provides link-level, switch-level, and blade-level failure protection. To make this effective, you must connect the iSCSI hosts to both iSR6200 blades. For details, see “Connecting

iSCSI Hosts to the iSR6200” on page 4-16.

Management

SANsurfer Router Manager and the CLI run on a management workstation used to configure, control, and maintain the router. Support platforms include Windows, Solaris, and Linux. The SANsurfer Router Manager utility is installed and executed on the workstation.

The router supports the following management interfaces:

 SANsurfer Router Manager is a graphical user interface (GUI) utility that

runs on a management workstation (see the iSR6200 Router Manager User’s Guide).

2–Planning

High Availability

 CLI is the command line interface that runs on the router; users can access

 SNMP provides router status, traps, and alerts (for details, see Appendix B).

Recovery

You should have a process in place to recover from a possible router failure. Consider the following when developing a recovery process for the router:

 Save all firmware image files (updates) in a safe, well-known place, because

 Save the router’s configuration (as a new file) after every configuration

 Save the router’s LUN mappings (as a new file) after every mapping

the CLI by means of Telnet or the serial port (see the iSR6200 CLI User’s Guide).

you may:

 Want to revert to a previous firmware version  Need the firmware image when replacing a single-blade router  Need the firmware image when adding a router to your site

change, because you may:

 Want to revert to a previous configuration  Need to configure a replacement blade in a single-blade router

change, because you may:

2–Planning Services

NOTE:

Services

You can configure your router to suit the demands of your environment using a variety of router services. Familiarize yourself with the following router services and determine which ones you need:

 Tel n et enables you to manage the router over a Telnet connection.

 Router management provides for out-of-band management of the router

 SNMP enables you to monitor the router using third-party applications that

 Want to duplicate the LUN mapping on a second router (for

redundancy)

For more details on recovering a router blade, see “iSR6200 Chassis

Blades” on page 7-1.

with SANsurfer Router Manager.

use SNMP.

Security

 Network time protocol (NTP) enables you to synchronize the router and

the workstation dates and times with an NTP server. NTP is disabled (not configured) by default.

 File transfer protocol (FTP) enables you to transfer files rapidly between

the workstation and router using FTP.

 Secure SHell (SSH) provides secure and encrypted connections to

traditionally non-encrypted services.

Passwords provide router security. SANsurfer Router Manager requires a password each time a user logs into the utility. After you are connected, SANsurfer Router Manager prompts for an administrative password before it accepts configuration changes.

The CLI also requires the user to enter a user ID and password to start. The CLI must be in an admin session to perform any set operations. An admin session requires a password.

The default password for both these management utilities is password for the default user ID of guest. The default administrative password is config.

After you have logged on, you can change the password using the utility’s security features.

4 Configuration

This chapter describes how to configure the iSR6200 router to support virtual port groups (VPGroups or VPGs) and LUN mapping.

Some storage arrays limit the number of LUNs exposed to a host to 256 LUNs. Each iSR6200 router blade supports up to four VPGs, making it possible for these storage arrays to present up to 1,024 LUNs per blade.

When configuring VPGs on the iSR6200 router, follow these guidelines:

 All Fibre Channel (FC) virtual ports from a single VPG must be part of only

one logical host on the storage array.

 Fibre Channel ports from different VPGs must not be part of the same logical

host on the storage array.

 A specific LUN can be presented to one and only one VPG. It can be

presented to other Fibre Channel hosts, but only one VPG on a specific iSR6200 router (chassis).

The following sections describe how to configure VPGs and the Fibre Channel arrays connected to them:

 “Enabling Virtual Port Groups” on page 4-2

 “Zoning Virtual Port Groups on the SAN” on page 4-9

 “Configuring Fibre Channel Array Hosts and LUN Assignments” on

page 4-12

 “Connecting iSCSI Hosts to the iSR6200” on page 4-16

 “Controlling per-Host LUN Access on the iSR6200” on page 4-22

ISR651101-00 E 4-1

4–Configuration Enabling Virtual Port Groups

Enabling Virtual Port Groups

Each iSR6250 router blade has one virtual port group (VPG) enabled by default, which gives the iSCSI hosts access to 256 LUNs. You can enable and configure additional VPGs to give the iSCSI hosts access to more than 256 distinct LUNS from a specific Fibre Channel target array.

Each blade has VPG 1 enabled by default; VPG 1 is the primary virtual port group and cannot be disabled. Enabling additional virtual port groups creates additional logical Fibre Channel adapter initiator ports on the fabric. These ports act as separate Fibre Channel adapter host ports, and additional 256 LUNs can be presented to each of them. With all four VPGs enabled, a single iSR6250 blade can access up to1,024 LUNs from a single target world wide port number (WWPN).

You can view Virtual Port Group information using the show vpgroups command in the CLI, as shown in the following example.

4–Configuration Configuring Fibre Channel Array Hosts and LUN Assignments

Configuring Fibre Channel Array Hosts and LUN Assignments

When configuring Fibre Channel array hosts, you must treat each iSR6200 virtual port group (VPG) as its own unique Fibre Channel host within the virtualized storage array. This means if you have only one VPG enabled, the iSR6200 will have only one host entity. If you enable two more VPGs, the iSR6200 presents three separate host entities to your storage array.

Each host entity must contain WWPNs from the same VPG. Figure 4-8 shows a correct configuration.

Figure 4-8. Correctly Configured Storage Array Using Virtual Port Groups

Do not simply group all Fibre Channel ports from the iSR6200 router into a single host entity. Doing so defeats the purpose of virtual port groups, limiting you to 256 LUNs. It will also cause problems when you later try to restore access to additional LUNS.

Connecting iSCSI Hosts to the iSR6200

Figure 4-13 shows presenting LUN 3 incorrectly. If an iSCSI host logged into both

VPG0 and VPG1, it would have access to LUN 3 through two virtual port groups. This is invalid and will lead to serious problems.

Figure 4-13. Incorrectly Presenting LUN 3

Presenting the LUN at different LUN indexes for each VP will confuse the iSCSI host MPIO software because it will see the same LUN WWLUNID at two different indexes. This would cause the multipath I/O (MPIO) driver to panic and show a blue screen. Without an MPIO driver, the system could corrupt data on the LUN, without crashing—a situation you want to avoid.

Connecting iSCSI Hosts to the iSR6200

Upon logging into a Fibre Channel target WWPN, an iSR6200 blade presents an iSCSI target to which iSCSI initiators can connect. This target is defined by its

4-16 ISR651101-00 E

iSCSI qualified name (IQN) string. To correctly connect iSCSI initiators to Fibre Channel targets through the iSR6200, it is important to understand the composition of the iSCSI target IQN string.

Connecting iSCSI Hosts to the iSR6200

The following example shows the anatomy of a sample IQN string from an iSR6200 router:

2. Product Name

3. iSR6200 Chassis Serial Number

4. Blade (b1 or b2)

5. VPGroup (01 through 04)

6. Fibre Channel target WWPN

Notice that the IQN string does not contain any information about which iSR6200 physical iSCSI port to which you are connecting. iSCSI load balancing and failover are handled by the iSCSI host and not on the iSR6200.

Also notice that the IQN string does not contain any information about which physical Fibre Channel port on the iSR6200 through which the Fibre Channel target device is attached.

You can view the complete list of IQN strings that your iSR6200 is presenting with the show presented_targets command in the CLI. For example:

iSCSI host LUN access is determined by the specific iSCSI target to which the host connects, and the LUNs to which the VPG has access from the storage array. Pay special attention to the VPG index of the IQN string you are logging into; it determines which group of LUNs on the storage array your host can access.

Controlling per-Host LUN Access on the iSR6200

In Figure 4-17, the iSCSI host has logged into iSCSI targets for both VPG1 and VPG2. The host can access both VPG1 and VPG2 LUNs 3 and 4.

Figure 4-17. iSCSI Host Logged into iSCSI Target for VPG1

Controlling per-Host LUN Access on the iSR6200

The iSR6200 allows multiple iSCSI initiators to connect to a single Fibre Channel target through a specific VPG. Controlling individual LUN access for each iSCSI host requires LUN mapping devices connected through the iSR6200.

NOTE:

Before proceeding with this section, be sure you have read and understand the previous sections of this chapter.

Figure 4-18 shows that even after logging into the VPG0 iSCSI target, the host

cannot access data LUNs on the storage array. To allow the iSCSI host access to each LUN, you must configure the iSR6200 using either SANsurfer Router Manager or the CLI.

5 Fibre Channel over IP

Fibre Channel over IP (FCIP) is a protocol used to transport Fibre Channel frames over TCP/IP, thus providing SAN over WAN capabilities. FCIP is commonly used to interconnect (merge) SANs that are separated by such a distance that a direct connection is cost prohibitive or technically unfeasible.

This chapter provides the following information:

 FCIP Attributes lists the attributes of FCIP implementation in the iSR6200.

 “Configuring FCIP” on page 5-2 explains the parameters used in setting up

FCIP, E_Port and F_Port extensions, WAN characteristics, data compression, bandwidth, and TCP window settings.

FCIP Attributes

The iSR6200 system FCIP implementation has the following attributes:

 Compatible with all Fibre Channel vendor fabrics (all Fibre Channel

switches)

 E_Port extension—Bridges same Fibre Channel vendor SANs (such as

Fibre Channel switches)

 F_Port extension—Does not merge fabrics

 Supported configurations:

 Two same-vendor Fibre Channel SAN islands  Direct connect from one N_Port to a remote SAN island

 Support for 1GbE and 10GbE connections:

NOTE:

No action is taken on any of the settings until you complete the last step. To cancel FCIP route configuration, enter q for any parameter.

To configure FCIP in the CLI:

1. From a command prompt, enter the fciproute add command.

2. Enable (or disable) the FCIP Interfaces FC & GE ports to be used by the FCIP route.

3. At the FC Port prompt, enter the number corresponding to the FC port to be used for this FCIP route.

4. At the GE Port prompt, enter the number corresponding to the GE port to be used for this FCIP route.

5. At the IP Address prompt, enter the router’s GE port IP address (the router being configured).

6. At the Subnet Mask prompt, enter the router’s GE port subnet mask.

7. At the Gateway IP Address prompt, enter the router’s GE port gateway IP address.

8. At the Remote IP Address prompt, enter the remote (peer) router’s IP address.

9. At the MTU Size prompt, specify the maximum transmission unit (MTU), either 0=Normal, 1=Jumbo, or 2=Other.

The MTU size is typically set to Normal (1,500 bytes). If all segments of the WAN support jumbo frames (9,000 bytes), select Jumbo. The Other option is typically used for WANs using encryption that requires the frame to be less than 1,500 bytes due to encryption overhead.

10. At the TCP Window Size prompt, specify the window size for the WAN as determined in “TCP Window Settings” on page 5-14.

5-4 ISR651101-00 E

5–Fibre Channel over IP

Configuring FCIP

11. At the Window Scaling prompt, enable or disable this setting. Window scaling must be enabled when using a Window Scaling Factor (see next step) greater than zero.

12. At the Window Scaling Factor prompt, enter a value from 0 through 9 as scaling factor, based on the TCP Window Size for the WAN specified in Step 10 (see “TCP Window Settings” on page 5-14).

13. (Optional) Changing the TCP port number at the TCP Port No. prompt should not be required. If you change this value, do not use a well-known TCP port number. The TCP port numbers on both the local and remote routers should be the same.

14. At the GE Port Speed prompt, select a GE port speed that matches that of the Ethernet switch port to which it is connected. QLogic recommends that you use a gigabit managed switch that is capable of automatically negotiating the port speed. If the Ethernet switch port speed is not capable of auto negotiation, set both the router and Ethernet switch to the same port speed.

15. At the Bandwidth, Mbit/sec prompt, enter a value from 1 through 1000 for the route bandwidth. To determine this value, see “Bandwidth

Limiting” on page 5-14.

16. At the VLAN prompt, enable or disable VLAN support as needed. Enable VLAN only if it is supported by the Ethernet switch.

17. At the FCIP SW Compression prompt, enable or disable data compression (see “Data Compression” on page 5-14 to determine if compression should be enabled).

E_Port Extension

The FCIP configuration used to interconnect (merge) two SANs separated by distance is referred to as an E_Port extension. The SANs to be interconnected (merged) must be made up of similar Fibre Channel switches, from the same manufacturer, and support ISLs using the E_Port protocol.

Figure 5-1 shows an example of a single FCIP route (single ISL).

The FCIP configuration used to connect a distant F_Port to a SAN is referred to as an F_Port extension. This configuration is used to connect remote (stranded) servers to a SAN or to connect remote storage to a SAN. In the F_Port extension configuration, one of the FCIP routers (local) is connected to a Fibre Channel switch (SAN), and the other FCIP router (remote) is directly connected to a Fibre Channel port on the server or storage.

Determining WAN Characteristics

To correctly configure an FCIP route for maximum performance and reliability requires precise understanding of the IP link (WAN) characteristics, including the following link characteristics:

 Link RTT

 Link data rate end-to-end:

5-8 ISR651101-00 E

 Available link bandwidth  Allocated link bandwidth

 Link (WAN) quality: congestion (dropped packets) and packet errors

Round-Trip Time

RTT is the time required for a packet to travel from the sender to the receiver, and then return to the sender. The router’s ping feature, either CLI or GUI, can help determine the RTT. The following is an example of the CLI ping command executed on GE port 1.

iSR6200 <1> (admin) #> ping

Link Data Rate

The available link data rate is not typically the same as the connection speed at the router’s GE port. The GE port is typically connected to a local IP switch with ports running at 1 gigabit. The provider of the long-distance connection (WAN) provides the link data rate. Table 5-2 lists some examples of data rates for commonly used WANs.

Table 5-2. WAN Data Rates

Link Type Speed

T1 and DS-1 1.554Mbps

T3 and DS-3 45Mbps

OC-1 50Mbps

OC-3 150Mbps

DS-5 400Mbps

Link Quality

OC-12 621Mbps

OC-24 1.5Gbps

In some configurations, the data rate (bandwidth) supported by the WAN may not be dedicated to a single application such as FCIP. The ability to set the router's FCIP bandwidth usage provides for such configurations (see “Bandwidth Limiting”

on page 5-14).

The link (WAN) quality can be difficult to determine; however, monitoring the router's statistics should provide an indication of the overall link quality. Typically, low link level errors are not seen at the router because they generally occur in the WAN.

The following TCP statistics are a useful indicator of WAN congestion or packet errors:

 TCP Received Duplicate ACKs—Receiving a duplicate ACK indicates that

the receiver did not receive the packet following the ACK’d packet (packet whose sequence number follows the ACK'd packet). This is typically the result of the following:

 Congestion: An IP switch or router somewhere in the WAN has

dropped the packet due to its inability to transmit or buffer the packet.

 Error: The packet was dropped somewhere in the WAN as a result of

the detection of a data error (corruption).

Configuring FCIP

 TCP Retransmit Timer Expired—The sender of a packet did not receive an

ACK for a packet within the retransmit time-out window. The sender will retransmit the packet. This is typically the result of the ACK being dropped somewhere in the WAN due to congestion or corruption of the ACK (less likely).

The following example shows the FCIP link statistics from the router’s CLI show statistics command. The TCP Timer Expired value consists of two counters:

 The upper 16 bits is a count of the number of retransmits resulting from

receiving duplicate ACKs (count = 34 in the example).

 The lower 16 bits is a count of the number of retransmits resulting from

retransmit time outs (count = 10 in the example).

Firewall

When configuring an FCIP route in a WAN containing a firewall, the TCP and server ports used by the FCIP route must be unblocked. Table 5-3 lists the well-known ports and server ports that require unblocking in the firewall.
