I have a stack of 2-7550zp's (running GZR08095g) using a static lag and connected to a another 7550 stack. Lag ports are 1/3/1 and 2/3/1. I've noticed that you get "normal" information when you issue "show int e 1/3/1 but issuing "show int e 2/3/1" returns invalid port. When I added any module ports from switch 2 the invalid port remained. Adding in a switch 1 port brought the lag up and I was able to see stats on the port.
Is this what other people are seeing on their lags? I've compared to 6450/7450/ICX7550-24F lags and I can see stats on both ports. I don't have any other newer icx's to compare. Maybe its a copper/fiber switch difference, maybe a module (icx7600-xgf-4port-40g-module) difference. Anyone else running the same module experiencing the same issue?
I'm not sure what happened to switch 2 (it persisted thru a boot) but the static lag is probably responsible for switch one blackhole. It really made it a PITA to troubleshoot lag port 2/3/1 when Ruckus denies the stats.
