EAPS and VRRP

[chieftan]

Quick question please:-

We are utilising 2 x BD8810 at the core of our network. VRRP is utilised and EAPS out to the edge switches.

VRRP setup is obviously 1 switch Primary and 1 Switch backup.

EAPS is set as Primary to edge switch - edge switch to Backup - backup to primary. This creates the ring for EAPS protection.

How much traffic would you expect to see traversing the ports on the backup core switch? I am using PRTG and am seeing some spurious information which may suggest that the backup switch is also handling traffic but from a VRRP perspective this should not be happening.

Thanks

As an example, not quite sure why you would see the traffic shown below on a back up syste,:-

Date Time Traffic Total (volume) Traffic Total (speed) Traffic In (volume) Traffic In (speed) Traffic Out (volume) Traffic Out (speed) Downtime Coverage
