Management Methods

The MIL-S3580 supports the following management methods:

 Console and Telnet Management 

Web-based Management

 SNMP Network Management

Console and Telnet Management

Console Management is done through the RS-232 Console Port. Managing the

MIL-S3580 in this method requires a direct connection between a PC and the

MIL-S3580. Telnet management is done over the network. Once the MIL-S3580

has an IP and is on the network, you can use Telnet to log in and change or view

the configuration.

SNMP Network Management

SNMP (Simple Network Management Protocol) provides a means to monitor and

control network devices, and to manage configurations, statistic collection,

performance, and security.

Data is passed from SNMP agents. SNMP agents are hardware & software

processes reporting activity in each network device to the workstation console.

The agent return information is contained in a MIB (Management Information

Base), which is a data structure that defines what is obtainable from the device and

what can be controlled.

2. Hardware Description

The Front Panel

The front panel of the MIL-S3580 consists of 24 auto-sensing 10/100Mbps

Ethernet RJ-45 Ports, two optional expansion slots, and a console port. The LED

Indicators are located on the front left panel of the Switch.

Power On

After all network cables are connected, plug the power cord into the power socket

on the back panel and the other end into a power outlet. Turn on the power using

the power switch on the back panel.

Check the front panel power indicator to see if power is properly supplied. The

switch uses a universal power supply that requires no additional adjustment.

Diagnostic Test

After the installation is completed and AC power is applied to the switch, the

system will automatically perform a diagnostic test. The PWR LED will come on.

Within 5 seconds, all LEDs will flash for a split second.

When the switch passes the self-test, the LEDs come on within 15 seconds on

ports that are populated and connected.

2.4. Trap Receiver

Figure 3-12. Trap Receiver Menu

A trap receiver is a management station designated by the switch to receive

SNMP traps sent from the switch. Use Trap Receiver screen to designate certain

community to receive trap(s) generated by the system. In the default

configuration, no trap receivers are configured and the authentication trap is

disabled. The trap's Host IP address is the IP address required.

2.5. Management Capability Setup

Figure 3-13. Management Capability Setup Menu

This menu allows you to enable/disable Web-Based management capability. If

disabled, there is no access to management function through the use of a Web

browser such as Microsoft Internet Explorer or Netscape.

2.6. Trap Filter Setup

Figure 3-14. Trap Filter Setup Menu

The system will generate a set of SNMP traps upon the occurrence of an event. By

checking a filter event, you are turning off the filter and enabling the trap associated

with that event. The trap will be sent to the community name(s) configured in the

Trap Receiver Menu.

3. Device Control Menu

Figure 3-15. Device Control Menu

Device Control Menu contains 15 submenus where you can add and modify

functions and features of the switch.

3.1. Switch Device Configuration

Figure 3-16. Switch Device Configuration Menu

Use <Space Bar> to toggle the Enable/Disable field and type in the appropriate

value in the Time and Priority fields.

x Spanning Tree Enable State is disabled by default on the MIL-S3580. The

switch uses the IEEE802.1D Spanning Tree Protocol (STP), when enabled,

to ensure that only one path at a time is active between any two nodes on the

network.

x Dynamic Entry Aging Time - This is the time, in seconds, that the switch

keeps an address of a device in the MAC address table. 300 seconds or 5

minutes is the default. The time can be set from 5 seconds to 999 seconds or

16.65 hours. A MAC address can also be entered in the static address table

to prevent aging out.

x Broadcast Storm Prevention can be set to 6%, 20% or Disabled. The

percentage indicates the allowance against the capacity. When disabled,

there is no limitation on the incoming rate of broadcast/multicast traffic,

otherwise limitation on broadcast traffic will be set to the configured

percentage.

x Ingress Filtering examines the tagged header of each tagged frame that

enters a port and determines whether the tagged frame and the port that

received the frame are members of the same VLAN. If they belong to the same

VLAN, the port accepts the frame. If they belong to different VLANs, the port

discards the frame. If Ingress filtering is disabled, any tagged frame is

accepted on any port on the switch. It does not matter whether the frame and

port belong to the same or different VLANs.

x

Per-Port Priority

allows port-based priorities. You can designate the priority

for the receiving port so that any frame received will be transmitted to the

destination port with the programmed priority. However, if the received frame

has a layer 3 priority (TOS or DiffServ), it will have precedence over

port-based priority. When set, all ports by default have the lowest priority

possible. If a priority different from lowest is wanted, the priority must be

changed for each individual port in the Port Configuration Menu.

x HOLB Prevention - Head Of Line Blocking occurs when many ports send

frames to the same output port. This puts the frames in contention for output

port and all frames must wait behind, thus the head of the line goes first. The

shared memory switching fabric architecture eliminates any possibility of

head-of-line blocking when this feature is enabled.

x When

is enabled, you can map the Type of Service of your choice

QoS

(according to IEEE 802.1p) to the 4 priority levels provided.

x There are 3 different modes of VLANs supported in this switch, 802.1Q,

Port-Based VLANs

and

MTU/MDU

. The choice you make here will

ultimately decide the VLAN mode and function for the entire switch. If one

mode is selected, the other two VLAN modes will have no effect on the

switch.

x GVRP Enable State is used with IEEE 802.1Q VLANs. GVRP enables the

switch to dynamically create 802.1Q compliant VLAN links with other

switches running GVRP. This reduces the chance for errors in VLAN

configuration by automatically providing VLAN ID (VID) consistency across

the network. You can use GVRP to propagate VLANs to other GVRP

switches instead of manually having to set up VLANs in each switch. In order

to activate GVRP without overlapping VLANs, follow these steps:

1. Assign static VLANs.

2. Take out ports that belong to assigned VLANs from Default VLAN.

3. Assign those ports to Local VID in Switch Port Configuration Menu.

4. Tag the uplink port in the Untagged Configuration Menu.

5. Turn on STP in Switch Configuration Menu.

6. Turn on GVRP in Switch Configuration Menu.

7. Update Configuration Setting.

8. Cold Start in System Start Menu.

x

IGMP Snooping

create lists of devices that are members of multicast groups. A multicast

group might consist of all users that want to see the company yearly meeting

on video. Video is a multicast application. IGMP Snooping enables the

switch to monitor the flow of queries from the devices and the routers. IGMP

Snooping improves the switch's performance by restricting the flow of

multicast packets to only those switch ports, which have devices receiving the

multicast (video).
