Products (1)

  • Cisco Catalyst 4000 Series Switches

Known Affected Releases

15.1(2)SG3.0.51 15.1(2.0)

Description (partial)

Symptom:
On a VSS with a dual sup 7E, configuiring a mac address as static and failing over will cause the standby to go into a bootloop.

Conditions:
Static mac configs are present. 
 - Switch#sh mac address-table static 
 - 100      03bf.c0a8.005c   static Te1/3/2,Te1/3/3,Te1/3/4

Once this has been configured and the supervisors failed-over, the standby sup will go into a boot loop with the following error message.

*Sep 11 20:49:12.131: %VSLP-5-RRP_ROLE_RESOLVED: Role resolved as STANDBY by VSLP
*Sep 11 20:49:49.518: %C4K_REDUNDANCY-2-IOS_VERSION_CHECK_FAIL: STANDBY:IOS version mismatch. Active supervisor version is 15.1(2)SG (cat4500e-UNIVERSALK9-M). Standby supervisor version is 15.1(2)SG (cat4500e-UNIVERSALK9-M). Redundancy feature may not work as expected.

On the primary we can see the mac address show up in the mcl mismatch

Проблема с VSS на 4500
Добрый день, коллеги. Столкнулся со странной проблемой, которая пока не поддается ни решению, ни гуглению. Имеется пара 4503 с Sup 7-E в VSS. Общий Uptime у VSS системы больше года. Переодически для проведения профилактики проводим redundancy force-switchover. Так вот после последнего force-switchover SLAVE коммутатор не подцепился к VSS.   В логах слейва: * | Apr  3 13:49:10.405: %C4K_IOSINTF-5-LMPHWSESSIONSTATE: Lmp HW session UP on slot 11 port 1. *Apr  3 13:49:12.448: %C4K_IOSINTF-5-LMPHWSESSIONSTATE: ...
