Possible issues with setting up IRF ring topology
We recently installed 4 5800AF-48G switches initially in a daisy chained toplogy. We then went ahead and configured IRF port 2 on SW1 and IRF port 1 on SW4 to complete the ring topology per the IRF configuration guide.
All the ports were enabled but when we check the IRF topology we see the following:
Topology Info
-------------------------------------------------------------------------
IRF-Port1 IRF-Port2
MemberID Link neighbor Link neighbor Belong To
4 DOWN -- UP 3 cc3e-5fa0-8698
3 UP 4 UP 2 cc3e-5fa0-8698
2 UP 3 UP 1 cc3e-5fa0-8698
1 UP 2 DOWN -- cc3e-5fa0-8698
When we do a show IRF configuration we see the following:
MemberID NewID IRF-Port1 IRF-Port2
1 1 Ten-GigabitEthernet1/0/53 Ten-GigabitEthernet1/0/54
2 2 Ten-GigabitEthernet2/0/53 Ten-GigabitEthernet2/0/54
3 3 Ten-GigabitEthernet3/0/53 Ten-GigabitEthernet3/0/54
4 4 Ten-GigabitEthernet4/0/53 Ten-GigabitEthernet4/0/54
All ports are enabled

port group interface Ten-GigabitEthernet1/0/54 mode enhanced
#
irf-port 2/1
port group interface Ten-GigabitEthernet2/0/53 mode enhanced
#
irf-port 2/2
port group interface Ten-GigabitEthernet2/0/54 mode enhanced
#
irf-port 3/1
port group interface Ten-GigabitEthernet3/0/53 mode enhanced
#
irf-port 3/2
port group interface Ten-GigabitEthernet3/0/54 mode enhanced
#
irf-port 4/1
port group interface Ten-GigabitEthernet4/0/53 mode enhanced
#
irf-port 4/2
port group interface Ten-GigabitEthernet4/0/54 mode enhanced
For switches configured with spanning tree I would expect that certain ports blocked but its been my understanding in a IRF configuration all ports are active and transfering traffic. Is this correct behavior or are we missing something?
Thanks in advance.

Re: Possible issues with setting up IRF ring topology
Swap the cable between 1 & 4 over with any of the other working cables?

Re: Possible issues with setting up IRF ring topology
Havent tried that yet as it is a brand new cable though we havent discounted the possibility it could be bad. What I would like to confirm is whether or not all ports should how as being in an UP status in an IRF configuration.

Re: Possible issues with setting up IRF ring topology
Just to close this out, we did finally figure out what the issue was. After we connected the SFP+ cable to complete the ring and enabled the respective ports, we needed to again initiate the following command to make the IRF configuration active:
irf-port-configuration active
Once we did this the IRF ports came online.
Thanks to all that replied.
