Hi,

I want to configure the supervisor redundancy protocol mode to be SSO. However, when I set the protocol to SSO it’s doesn’t change the operational mode.

Here’s a screenshot from the active supervisor:

localhost(s1)(config-redundancy)#show redundancy status
my state = ACTIVE
peer state = STANDBY WARM
Unit = Primary
Unit ID = 1

Redundancy Protocol (Operational) = Route Processor Redundancy
Redundancy Protocol (Configured) = Route Processor Redundancy
Communications = Up
Ready for switchover

Last switchover time = 1:10:19 ago
Last switchover reason = Other supervisor stopped sending heartbeats
localhost(s1)(config-redundancy)#show redundancy status
my state = ACTIVE
peer state = STANDBY WARM
Unit = Primary
Unit ID = 1

Redundancy Protocol (Operational) = Route Processor Redundancy
Redundancy Protocol (Configured) = Route Processor Redundancy
Communications = Up
Ready for switchover

Last switchover time = 1:10:52 ago
Last switchover reason = Other supervisor stopped sending heartbeats

localhost(s1)(config-redundancy)#protocol sso

localhost(s1)(config-redundancy)#show redundancy status
my state = ACTIVE
peer state = STANDBY WARM
Unit = Primary
Unit ID = 1

Redundancy Protocol (Operational) = Route Processor Redundancy
Redundancy Protocol (Configured) = Stateful Switchover
Communications = Up
Ready for switchover

Last switchover time = 1:20:36 ago
Last switchover reason = Other supervisor stopped sending heartbeats

Please advise.

Hardware: Arista DCS-7504N with 2 SUB
Software image version: 4.21.3F

Thanks,
Waleed

Hi Waleed,

Could you please confirm if both supervisors have the same version of code? You could check this using the command “session peer-supervisor show version”. Pls see this article https://eos.arista.com/eos-4-20-5f/sso-support-for-jericho/ for more information. HTH

Hi..

I upgraded the other supervisors, and now it’s working as expected.
