Hello all,
I keep getting the below alert while i'm running failover testing scenarios. Please let me know if there's anything missing or anyone experienced same issue before.. After I issue 'redundancy force-switchover' the fail-over happens but one of the VSL links is put in suspended mode.
*Sep 15 19:21:15.283: %EC-SW2-5-CANNOT_BUNDLE2: Te1/5/4 is not compatible with Te1/6/4 and will be suspended (Operational flow control receive of Te1/5/4 is on, Te1/6/4 is disagree)
*Sep 15 19:21:15.667: %EC-SW2-5-CANNOT_BUNDLE2: Te2/5/4 is not compatible with Te2/6/4 and will be suspended (Operational flow control receive of Te2/5/4 is disagree, Te2/6/4 is on)

2 Po2(RU) - Te2/5/4(w) Te2/6/4(P)
##Setup
6506E-SUP2T VSS

Te1/5/4, Te1/6/4 - Te2/5/4, Te2/6/4 are 2 x 10Gb VSL (Copper)
Gi1/2/48 is the heartbeat (Copper)

Hi,
You configuration is correct. You also have an issue with Te2/5/4(w) (waiting to be bundled).
Can you test by putting both 10Gig ports on the same Sup?
it would be 1/5/4 and 1/5/5 for each chassis.

Hi Reza,
Te2/5/4 (w) is connected to Te1/5/4 (s). I will try to use 1/5/4,1/5/5 for VSL and post the output soon. I feel like i'm hitting a bug...
Thanks,

Hey Reza,
VSL Links seem to be okay when I'm using Te1/5/4&Te1/5/5 <-> Te2/5/4&Te2/5/5.
But using Te1/5/4&Te1/6/4 will give me more redundancy. Is there any reason why the port bundling fails when using two different SUP interfaces?
