To aid in management, the Catalyst 2600 allows you to obtain a variety of status, statistic, and diagnostic information. This chapter provides information on the following:
For information about setting up a console session, refer to the section "Planning for Configuration and Management."
Note The Catalyst 2600 allows LAN Network Manager LLC frames to flow through the switch. Therefore, communication between LAN Network Manager and existing source-route bridges and controlled access units is maintained. However, some error reporting functions and ring map functions might be lost for the rings attached to the Catalyst 2600.
The Catalyst 2600 allows you to view status information and statistics for individual ports or for the Catalyst 2600 as a whole. This information is displayed on several panels that are accessible from the Status/Statistics Menu.
To access the Status/Statistics Menu, select Status/Statistics on the Main Menu. The Status/Statistics Menu (Figure 7-1) is displayed.
Figure 7-1: Status/Statistics Menu Panel
You can view status information for:
- The Catalyst 2600 and any installed Universal Feature Cards (UFCs)
- Each port
- Each defined TokenChannel
To view general information about the Catalyst 2600 and any UFCs installed, select Module Information on the Status/Statistics Menu. The Module Information panel (Figure 7-2) is displayed.
Figure 7-2: Module Information Panel
The following information is displayed on this panel:
- Module--The module number. The Catalyst 2600 is listed as Module 0. UFCs will be listed as Module 1 and Module 2.
- Status--Whether the module is up or down.
- Type--The type of module (Base Switch or UFC).
- Revision--The revision level of the module.
- Ports--The number of ports on the module.
- Up Time--The amount of time in hours, minutes, and seconds that the module has been up (since the last reset).
You cannot change the information that appears on this panel.
To view status information for each port of the Catalyst 2600, select Port Status on the Status/Statistics Menu. The Port Status panel (Figure 7-3) is displayed.

- State--The operational status of the port.
- Link--Indicates whether the port is Up (open) or Down (closed).
- Configuration Type--The type of configuration mechanism used for the port.
- Auto--Speed, Mode, and Duplex are automatically set by the Catalyst 2600
- Fixed--Allows you to manually set Speed, Mode, and Duplex.
- Speed--The speed of the port in Mbps. The prefix RSA means the speed was automatically sensed and set by the Catalyst 2600. The prefix FIX means the speed was set to a fixed value via configuration.
- Mode--Indicates whether the port is used for shared or dedicated media.
- Port Mode--In port mode only a dedicated connection to a station is supported. The Tx/Rx pinouts are the same as a concentrator's.
- Adapter Mode--In adapter mode, the port operates like a station. The connection may be dedicated or shared. The Tx/Rx pinouts are the same as an adapter's.
- Duplex--Whether the port is operating in full or half duplex mode. Changes to the duplex settings are made immediately by the Catalyst 2600.
- Configuration Loss--The configuration loss threshold. Configuration loss occurs when a port completes a connection, allows data traffic to flow, and subsequently closes. This threshold is used to control the number of configuration losses that can occur within a specified time. When the threshold is exceeded, the port is disabled and must be enabled via this panel or an SNMP manager.
You cannot change any information on this panel. To change any of the port parameters, refer to the section "Configuring Port Parameters."

Figure 7-13: Current Spanning Tree Panel
The following information is displayed on this panel:
- Hello Time--The time (in seconds) that the root waits between sending configuration messages. This time is advertised by the root and used by all devices and switches in the active topology of the spanning-tree network.
- Max Message Age--The time at which the configuration message used by the spanning-tree algorithm should be discarded. This time is advertised by the root and used by all devices and switches in the active topology of the spanning-tree network.
- Forward Delay--The time the root waits between transitions from listening to learning, and from learning to forwarding. This time is advertised by the root and used by all devices and switches in the active topology of the spanning-tree network.
- Root--The priority and MAC address of the device in the spanning tree that this Catalyst 2600 has accepted as the root device.
- Root Port--The number of the port on this Catalyst 2600 that is closest to the root. This Catalyst 2600 communicates with the root through this port. If there is no root port, this Catalyst 2600 has been accepted as the root of the spanning-tree network.
- Port ID--The port ID that is used to determine the role of the port in the spanning tree. The port ID is expressed in the form port priority.port number.
- Port Cost--The cost associated with each port. Lower numbers are generally assigned to ports attached to faster media (such as FDX or TokenChannel), and higher numbers are generally assigned to ports attached to slower media (such as 2400-baud modem links).
- Port Status--The current status of this port within the spanning tree. Possible values are:
- DSB (Disabled)
- BLK (Blocked)
- LSN (Listening)
- LRN (Learning)
- FWD (Forwarding)
- The rules that define the state of the port are as follows:
- A port on a network segment that contains no other switch or bridge is always forwarding.
- If two ports of the Catalyst 2600 are connected to the same network segment and there is no other bridge or switch, the port with the lower ID is forwarding and the other is blocked.
- When the switch is booted, all ports are blocked initially, and then some of them change to a different state: listening, learning, and forwarding, in that order. To see the change in states you must repeatedly exit from this menu, and then select it again. All ports that are going to change states from blocking to forwarding will have done so after two to three times the value of:
- Switch Maximum Message Age + (2 x Switch Forward Delay)
- Designated Cost--The cost for a packet to travel from this port to the root in the current spanning-tree configuration. The slower the media, the higher the cost.
- Designated Switch/Bridge ID--The priority and MAC address of the device through which this port has determined it must communicate with the root of the spanning tree.
- Designated Port ID--The port on the designated bridge through which this Catalyst 2600 will communicate with the root of the spanning tree. This information is useful if the Catalyst 2600 is the designated bridge on one or more network segments.
- # Topo Changes--The number of topology changes, that is, the number of times the port has entered the forwarding state plus the number of times the port has made the transition from forwarding to blocking. The counter is reset when the switch is reset or the spanning tree is turned on.
- Time Since Last Change--The time since the port last entered the forwarding state or made the transition from forwarding to blocking.
