Hello UCB,
I would go on in this way that I use:
a) core720# sh ethercha sum
find the member links of Po10
let's suppose it is Gi4/1 a member link of Po10
do
b) sh cdp n g4/1
you find an hostname of next switch
c)
telnet to that switch by name or ip address
d) do
sh mac-address-table address 0050.564b.00b6
do sh cdp n of the interface listed in the output of previous command:
if no cdp neighbor is found or an IP phone is found the search is terminated
otherwise repeat steps c) e d)
Hope to help
Giuseppe

Hello UCB,
out Po41 formed by Gi1/0/41(P) Gi1/0/42(P) Gi1/0/43(P) and using LACP you probably have a server with multiple NICs using teaming
your search is terminated
0050.56 OUi :
00-50-56 (hex) VMWare, Inc.
005056 (base 16) VMWare, Inc.
44 ENCINA AVENUE
PALO ALTO CA 94301
UNITED STATES
This is a VMware system with 3 NICs in bundle
Hope to help
Giuseppe
