Hi


I need some help to login on Standby module, to reload standby module and get Sh tech and other information from the standby module.


Thanks in advance.

Hello Jagdev,


access to standby processor is practically useless as you can see in this example


Mod  Redundancy role     Operating mode      Redundancy status
----+-------------------+-------------------+----------------------------------
3   Active Supervisor   SSO                 Active                           
4   Standby Supervisor  SSO                 Standby hot              



SW-TO-CRN-SM-C-5#session module 4
Connecting to standby virtual console
Type "exit" or "quit" to end this session


switch-standby-console#sh ver


Standby console disabled.
Valid commands are: exit, logout


switch-standby-console#exit
switch#


you can reload the standby processor with

hw-module module 4 reset
Proceed with reload of module? [confirm]

answer yes or type enter


Note: you need to use as module number the slot number of the standby processor you can see this

at the end of sh module and using sh redundancy

Example of sh redundancy:


W-TO-CRN-SM-C-5#sh redundancy
Redundant System Information :
------------------------------
       Available system uptime = 1 year, 9 weeks, 2 days, 1 hour, 32 minutes
Switchovers system experienced = 8
              Standby failures = 1
        Last switchover reason = user forced


                 Hardware Mode = Duplex
    Configured Redundancy Mode = Stateful Switchover
     Operating Redundancy Mode = Stateful Switchover
              Maintenance Mode = Disabled
                Communications = Up


Current Processor Information :
-------------------------------
               Active Location = slot 3
        Current Software state = ACTIVE
       Uptime in current state = 1 year, 2 weeks, 1 day, 17 hours, 16 minutes
                 Image Version = Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500-IPBASEK9-M), Version 12.2(50)SG1, RELEASE SOFTWARE (fc2)

        Configuration register = 0x2


Peer Processor Information :
----------------------------
              Standby Location = slot 4
        Current Software state = STANDBY HOT
       Uptime in current state = 1 year, 2 weeks, 1 day, 16 hours, 59 minutes

        Configuration register = 0x2




A better way to do this is :


redundancy reload peer


as explained above you cannot get sh tech of standbty processor unless you use


redundancy force-switchover


to exchange roles of the two supervisors!


said this, there are few reasons to get standby sup info they need to be identical and to run the same IOS image in order to build an SSO pair


Hope to help
