Changing the Manager and Operator Passwords

There are two levels of management access on the AT-9400 Switch: manager and operator. When you log in as manager, you can view and configure all of a switch’s operating parameters. When you log in as an operator, you can only view the operating parameters; you cannot change any values.
You log in as a manager or an operator when you enter the appropriate username and password when you start a management session. The default password for manager access is “friend.” The default password for operator access is “operator.” Passwords are case sensitive.
This section contains these two procedures:
“Changing the Manager or Operator Password” on page 35
“Resetting the Manager Password” on page 37
The first procedure allows you to change the manager or operator password. The second procedure allows you to bypass the manager password in the event you lose or forget it.

9. After making changes, type R until you return to the Main Menu. Then type S to select Save Configuration Changes.
Resetting the
Manager
Password
This procedure can be used to bypass the login on the switch in the event you forget the manager password. This procedure must be performed from a local management session.
Caution
With this procedure, any person with physical access to the switch can gain access to the unit’s management software without a user name or password. For this reason, all AT-9400 Switches should be maintained in a locked wiring closet or other secure location to prevent unauthorized management access.
Note
This procedure requires rebooting the switch. Some network traffic may be lost.
To reset the manager password, perform the following procedure:
1. Establish a local management session with the switch.
2. Reboot the switch. Refer to “Rebooting the Switch” on page 43 for instructions.
3. When the switch displays “Press <Ctrl> B to go to Boot prompt,” type S or s.
The switch, without acknowledging the key input, continues with the process of initializing the management software.
4. At the completion of the initialization process, press Return.
You are automatically logged on with manager privileges. The command line interface is displayed.
5. Change the manager’s password from either the command line interface or the menus interface. For instructions on how to change the password from the menus interface, refer to “Changing the Manager or Operator Password” on page 35.
This completes the procedure for resetting the manager password. You can continue to manage the switch or quit from the management session. You must use the new password the next time you log on to the switch at the start of a management session.
Section I: Basic Operations 37
Chapter 1: Basic Switch Parameters

Setting the System Time

This procedure explains how to set the switch’s date and time. Setting the system time is important if you configured the switch to send traps to your management stations. Traps from a switch where the time has not been set do not contain the correct date and time. Therefore, it becomes difficult for you to determine when the events represented by the traps occurred.
It is also important to set the system time if you intend to use the Secure Sockets Layer (SSL) certificate feature described in, Chapter 34, ”PKI Certificates and SSL” on page 611. Certificates must contain the date and time when they are created.
There are two ways to set the switch’s time. One method is to set it manually. The AT-9400 Switch has an onboard battery that maintains the date and time even when the unit is powered off or reset. For instructions, refer to “Setting the System Time Manually,” next.
The second method uses the Simple Network Time Protocol (SNTP). The AT-S63 Management Software is shipped with the client version of this protocol. You can configure the AT-S63 Management Software to obtain the current date and time from an SNTP or Network Time Protocol (NTP) server located on your network or the Internet. For instructions, refer to “Setting the System Time from an SNTP or NTP Server” on page 40.
SNTP is a reduced version of the NTP. However, the SNTP client software in the AT-S63 Management Software is interoperable with NTP servers.
The local subnet on the switch where the SNTP server is a member must have a routing interface. The switch uses the IP address of the routing interface as its source address when communicating with the server. To configure routing interfaces using the menus interface, refer to Chapter 29, “Internet Protocol Version 4 Routing Interfaces” on page 547 in this guide.
Note
Prior to version 2.0.0 of the AT-S63 Management Software, the SNTP server had to be a member of the switch’s management VLAN. This restriction no longer applies. The SNTP server can be located on any local subnet of the switch, provided the subnet has a routing interface.
Note
The default system time on the switch is midnight, January 1, 1970.

For AT-9400 Switches that support IPv4 routing, such as the AT-9424Ts and AT-9448Ts/XP switches, this field displays the IP address of the next hop of the switch’s default route. The switch uses the default route when it receives a network packet for routing, but cannot find a route for it in the routing table. This field will contain
0.0.0.0 if no default route is defined on the switch.
For AT-9400 Switches that do not support IPv4 packet routing, such as the AT-9424T/GB and AT-9424T/SP switches, this field displays the default gateway address. This is the IP address of a router interface on your network. It represents the next hop to reaching a remote network device, such as a remote management workstation or a syslog server, when the switch’s local interface and the remote device are on different subnets. The default value is 0.0.0.0.

4. Adjust the following parameters as necessary.
Note
A change to a parameter is immediately activated on the port.
0 - Description
You use this option to assign a description to a port, from 1 to 15 alphanumeric characters. Spaces are allowed, but you should not use special characters, such as asterisks or exclamation points. (You cannot set a port description if you are configuring more than one port.)
1 - Status
You use this option to enable or disable a port. When disabled, a port does not forward frames to or from the node connected to the port.
You might want to disable a port and prevent packets from being forwarded if a problem occurs with the node or cable connected to the port. After the problem has been fixed, you can enable the port again to resume normal operation.
You might also want to disable a port that is not being used to secure it from unauthorized connections.
Possible settings for this parameter are:
Enabled - The port receives and forwards packets. This is the default setting.
Disabled - The port does not receive or forward packets.
Note
Option 2, HOL Blocking Prevention, is described in “Configuring Head of Line Blocking” on page 69. Option 3, Flow Control, is described in “Configuring Flow Control and Back Pressure” on page 71. Option 4, Filtering, is described in “Configuring Port Filtering” on page 73. Option 5, Rate Limiting, is described in “Setting Up Rate Limiting” on page 75.
6 - Negotiation
You use this option to configure a port for Auto-Negotiation or to manually set a port’s speed and duplex mode. The default is Auto for Auto-Negotiation.
Note
When you set negotiation to Manual, items 7 (Speed), 8 (Duplex), and 9 (MDI Crossover) are displayed.
66 Section I: Basic Operations
AT-S63 Management Software Menus User’s Guide
If you select Auto for Auto-Negotiation, which is the default setting, the switch sets speed, duplex mode, and MDI crossover for the port automatically. The switch determines the highest possible common speed between the port and its end node and sets the port to that speed. This helps to ensure that the port and the end node are operating at the highest possible common speed.
Note the following items concerning the operation of Auto-Negotiation on a switch port:
A 10/100/1000Base-T twisted pair port must be set to set to Auto-
Negotiation to operate at 1000 Mbps. You cannot manually configure a 10/100/1000Base-T twisted pair port to 1000 Mbps.
In order for a switch port to successfully autonegotiate its duplex
mode with an end node, the end node should also be using Auto­Negotiation. Otherwise, a duplex mode mismatch can occur. A switch port using Auto-Negotiation defaults to half-duplex if it detects that the end node is not using Auto-Negotiation. This can result in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.
To avoid this problem when connecting an end node with a fixed
duplex mode of full-duplex to a switch port, disable Auto­Negotiation on the port and set the port’s speed and duplex mode manually.
When a twisted pair port is set to Auto-Negotiation, the MDI/MDI-X
setting for the port is locked at auto-MDI/MDI-X. The switch automatically determines the correct MDI/MDI-X setting. You cannot set MDI/MDI-X manually.
When Auto-Negotiation is disabled on a twisted pair port, the auto-
MDI/MDI-X feature on a port is also disabled, and the port defaults to the MDI-X configuration. Consequently, if you disable Auto­Negotiation and set a port’s speed and duplex mode manually, you might also need to set the port’s MDI/MDI-X setting as well.
An SFP or GBIC module uses Auto-Negotiation to set its speed
and duplex mode. If the SFP or GBIC is paired with a twisted pair port whose speed and duplex mode were set manually, the speed reverts to Auto-Negotiation when an SFP or GBIC module establishes a link with an end node.
7 - Speed
This item is only available when Negotiation is set to Manual. Type 7 to toggle between the following selections:
10 Mbps
100 Mbps
Section I: Basic Operations 67
Chapter 2: Port Parameters
1000 Mbps (Applies only to 1000Base SFP and GBIC modules. This selection should not be used. An SFP or GBIC module should use Auto-Negotiation to set its speed and duplex mode.)
8 - Duplex
This item is only available when Negotiation is set to Manual. The possible settings are full-duplex and half-duplex.
9 - MDI Crossover
This item is only available when Negotiation is set to Manual.
This selection sets the wiring configuration of a twisted pair port. The configuration can be MDI or MDI-X.
The twisted pair ports on the switch feature auto-MDI/MDI-X. They configure themselves automatically as MDI or MDI-X when connected to an end node. This allows you to use a straight-through twisted pair cable when connecting any network device to a port on the switch.
When a port is using Auto-Negotiation to set its speed and duplex mode, the only available setting for this item is Auto. The port automatically sets its MDI/MDI-X setting.
If you disable Auto-Negotiation on a port and set a port’s speed and duplex mode manually, the auto-MDI/MDI-X feature is also disabled. A port where Auto-Negotiation has been disabled defaults to MDI-X. Disabling Auto-Negotiation may require that you manually configure a port’s MDI/MDI-X setting using this option or that you use a crossover cable.
The final three parameters on the Port Configuration menu are:
X - Reset Port
This item resets the selected port. For more information, see “Resetting a Port” on page 77.
F - Force Renegotiation
This item prompts the port to autonegotiate with the end node. For more information, see “Forcing Port Renegotiation” on page 78.
D - Set Port Configuration to Defaults
This item resets all port settings to the default values. For more information, see “Resetting the Port Configuration to the Default Settings” on page 79.

68 Section I: Basic Operations

Configuring Head of Line Blocking

Head of line (HOL) blocking is a problem that occurs when a port on a switch becomes oversubscribed. An oversubscribed port is receiving more packets from other switch ports than it can transmit in a timely manner.
An oversubscribed port can prevent other ports from forwarding packets to each other because ingress packets on a port are buffered in a First In, First Out (FIFO) manner. If the head of an ingress queue consists of a packet destined for an oversubscribed port, the ingress queue is not able to forward any of its other packets to the egress queues of other ports.
A simplified version of the problem is illustrated in Figure 16. It shows four ports on a switch. Port D is receiving packets from two ports—50% of the ingress traffic on port A and 100% of the ingress traffic on port B. Not only is port A unable to forward packets to port D because the latter’s egress queues are filled with packets from port B, but it is also unable to forward traffic to port C because its ingress queue has frames destined to port D that it is unable to forward.

The HOL Limit parameter can help prevent this problem from occurring. This parameter sets a threshold on the utilization of a port’s egress queue. When the threshold for a port is exceeded, the switch signals other ports to discard packets to the oversubscribed port.

70 Section I: Basic Operations

Configuring Flow Control and Back Pressure

A switch port uses flow control to control the flow of ingress packets from its end node when operating in full-duplex mode.
A port using flow control issues a special frame, referred to as a PAUSE frame, as specified in the IEEE 802.3x standard, to stop the transmission of data from an end node. When a port needs to stop an end node from transmitting data, it issues this frame. The frame instructs the end node to cease transmission. The port continues to issue PAUSE frames until it is again ready to receive data from the end node.
The default setting for flow control on a switch port is disabled.
Back pressure performs much the same function as flow control. Both are used by a port to control the flow of ingress packets. Flow control applies to ports operating in full-duplex; back pressure applies to ports operating in half-duplex mode.
AT-S63 Management Software Menus User’s Guide
When a twisted pair port on the switch operating in half-duplex mode needs to stop an end node from transmitting data, it forces a collision. A collision on an Ethernet network occurs when two end nodes attempt to transmit data using the same data link at the same time. A collision causes the end nodes to stop sending data.
When a switch port needs to stop a half-duplex end node from transmitting data, it forces a collision on the data link, which stops the end node. After the switch is ready to receive data again, the switch stops forcing collisions. This is called back pressure.
The default setting for back pressure on a switch port is disabled.
To set up flow control or back pressure, perform the following procedure:
1. From the Main Menu, type 1 to select Port Configuration.

Configuring Port Filtering

If the performance of your network is affected by heavy traffic, you can use these parameters to restrict ingress and egress broadcast packets as well as unknown unicast and multicast packets forwarded by a port. Activating this feature on a port causes the port to discard all packets of the type you specified. For example, you might configure a port to discard all ingress and egress broadcast packet or perhaps just unknown unicast egress packets. The default setting for each filter is disabled.

Setting a Switch’s Enhanced Stacking Status

The enhanced stacking status of the switch can be master, slave, or unavailable. Each status is described below:
Master switch - The master switch is your entry point for managing the
switches of a stack. Starting a local or remote management session on a master switch gives you management access to all the switches in the stack.
Slave switch - A slave switch can be remotely managed through a
master switch or independently, such as through a local session.
Unavailable - A switch with an unavailable stacking status is not part of
an enhanced stack must be managed independently, either locally or remotely.
Note
The default setting for a switch is slave.
Note
You cannot change the stacking status of a switch through enhanced stacking. You must access the switch directly, either through a local or remote session, to change its stacking status.
To adjust a switch’s enhanced stacking status, perform the following procedure:

Setting the Authentication Failure Trap

As mentioned in the SNMP Overview section in this chapter, a trap is a message sent by the switch to a management workstation or server to signal an operating event, such as when the device is reset.
An authentication failure trap is similar to other the traps. It too signals an operating event on the switch. But this trap is somewhat special because it relates to SNMP management. A switch that sends this trap could be indicating an attempt by someone to gain unauthorized management access using an SNMP application program to the switch. There are two events that can cause a switch to send this trap:
An SNMP management station attempts to access the switch using an
incorrect or invalid community name.
An SNMP management station tried to access a closed access
community string, to which its IP address is not assigned.
AT-S63 Management Software Menus User’s Guide
Given the importance of this trap to the protection of your switch, the management software allows you to disable and enable it separately from the other traps. If you enable it, the switch will send this trap if either of the above events occur. If you disable it, the switch will not send this trap. The default is disabled.
If you enable this trap, be sure to add one or more IP addresses of trap receivers to the community strings so that the switch will know where to send the trap if it needs to.
To enable or disable the authentication trap, perform the following procedure:
1. From the Main Menu, type 5 to select System Administration.
The System Administration menu is shown in Figure 1 on page 32.
2. From the System Administration menu, type 5 to select SNMP Configuration.
