1) Those are the 6 etherchannels between the FWSM and the switch.
When you reload switch 1, you only see 6 for switch 2. Once everything is
back, you will see 2 Pos for switch 1 and switch 2 each with 6 ports.
2) Not sure what you did, but if one port left the channel, that status
should be Te1/50(D) - D for down, and the port-channel should still
function.

I've just done it (the lab).
There were a couple of things that I would like to understand,
if someone has a clue.
1) show etherchannel summary showed some bundles that the config
had no hint about:
Group Port-channel Protocol Ports
------+-------------+-----------+-------------------------------------------
---- 1 Po1(RU) - Te1/1/4(P) Te1/1/5(P) 2 Po2(RU) - Te2/1/4(P) Te2/1/5(P) 3 Po3(SU) PAgP Te1/2/2(P) 4 Po4(SU) LACP Gi1/3/1(P) 10 Po10(RD) PAgP Te1/2/1(D) 580 Po580(SD) - 596 Po596(SD) -This is some time after a switchover.
While stable, they showed: 580 Po580(SD) - 596 Po596(SU) - Gi2/4/1(P) Gi2/4/2(P) Gi2/4/3(P) Gi2/4/4(P) Gi2/4/5(P) Gi2/4/6(P)
but all Gi ports where config default.
2) That switchover was produced by preemtion, and one of the etherchannels stayed down from the 4948 perspective:
pod1-4948-10G#ping Protocol [ip]: Target IP address: 10.252.11.1 Repeat count [5]: 1000000 Datagram size [100]: 4000 Timeout in seconds [2]: Extended commands [n]: Sweep range of sizes [n]: Type escape sequence to abort. Sending 1000000, 4000-byte ICMP Echos to 10.252.11.1, timeout is 2 seconds: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!! 2d16h: %EC-5-UNBUNDLE: Interface TenGigabitEthernet1/50 left the port-channel Po rt-channel3............................................ ...................................................................... ...................................................................... ........ pod1-4948-10G#sh etherc sum Flags: D - down P - in port-channel I - stand-alone s - suspended R - Layer3 S - Layer2 U - in use f - failed to allocate aggregator u - unsuitable for bundling w - waiting to be aggregated d - default port
Number of channel-groups in use: 1 Number of aggregators: 1
Group Port-channel Protocol Ports ------+-------------+-----------+------------------------------------------- ---- 3 Po3(SU) PAgP Te1/49(P) Te1/50(P)
pod1-4948-10G#ping 10.252.11.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.252.11.1, timeout is 2 seconds: ..... Success rate is 0 percent (0/5)
Any ideas ? -Carlos
