Supervisor Redundancy for the Cisco 6500 Router

We currently have the following configuration:

STB_6509#sho mod

Mod Ports Card Type                              Model              Serial No.

--- ----- -------------------------------------- ------------------ -----------

  1   10  WiSM WLAN Service Module         WS-SVC-WISM-1-K9  

  2   24  CEF720 24 port 1000mb SFP         WS-X6724-SFP      

  5    2  Supervisor Engine 720 (Active)         WS-SUP720-3B      

Mod  Sub-Module                  Model              Serial       Hw     Status

---- --------------------------- ------------------ ----------- ------- -------

  1  Centralized Forwarding Card   WS-SVC-WISM-1-K9-D

  2  Centralized Forwarding Card   WS-F6700-CFC      

  5  Policy Feature Card 3            WS-F6K-PFC3B     

  5  MSFC3 Daughterboard           WS-SUP720         

I would like to add a redundant supervisor blade to the 6509 that is in production. Can this be done plug and play and require no reload.

Are all WS-SUP720-3B the same as far as memory etc... or can I buy any used WS-SUP720-3B and it will work properly.

Thanks,

Tom

Supervisor Redundancy for the Cisco 6500 Router

Hi Tom

You can insert a second sup 720 in slot 6 and configure it for SSO mode to achieve redundancy. The sup 720's by default get shipped with 512 MB Dram which is the minimum required to run any of the latest IOS releases.

You will need to schedule a maint: window for configuring SSO mode as it will require a reboot.

Here is the procedure to configure SSO mode on 4500 platform. However the same is applicable for 6500 as well-

Note:The active and standby supervisor should have the same IOS version and configuration for SSO to work.
