Dear all,
I am currently dealing with 2 IE-2000-8TC-G-E (FW 15.2.4) and 2x Nexus 5596UP. The Nexus switches are connected via vPC and the 2 IE-2000 switches are connected via a port-channel to each switch and all is ok. So far so good.
Now I need to enable MRP on the 2 IE-2000 and as soon as I do that, I can see a mac flap on the IE-2000. please see the partial config below:
IE-2000_1
Manager:
mrp ring 1
mode manager
vlan-id 48
int range fa1/7-8
switchport mode trunk
swi non
mrp ri 1
int po1
desc Uplink to Core
swi mode trunk
swi non
int ran g1/1-2
swi mo trunk
swi non
channel-group 1 mode passive
IE-2000_2
Client:
mrp ring 1
mode client
vlan-id 48
int ran fa1/7-8
swi mode trunk
swi non
mrp ring 1
int po1
desc Uplink to Core
swi mode trunk
swi non
int ran g1/1-2
swi mo trunk
swi non
channel-group 1 mode passive
The MRP Ring is closed and on the IE-2000_1 ( MRP Manager) port fa1/8 is block, shown in the output of the show mrp ring command.
As long as the 2nd IE-2000 switch is not connected to the Coreswitches, all is good, but as soon it connects, the switches report macflap in vlan 48 seen on port fa1/7 and po1.
Any help is much appreciated.
Cheers
Thorsten
