Hi,
Has anyone configured Layer 3 port channel on Cisco 6509 switches which are connected over dark fiber between two buildings?
Is it possible? please let me know.

Hi,
Yes, defiantly possible. As long as all physical links have the same speed and duplex.

hi.
I agree with reza sharifi. if we use port channel on any switch then each links in port channel have same spped and duplex.

Dark fiber - between buildings - don't recall if I've done that, but have done L3 port-channels across fiber between 6500s. So, yes it should be possible.

I ping 100 packets via this router. the counts are getting incremented as follows,
c2921#sh policy-map int g0/0
GigabitEthernet0/0
Service-policy output: pdestip
Class-map: cdestip (match-all)
0 packets, 0 bytes
30 second offered rate 0000 bps, drop rate 0000 bps
Match: access-group 190
QoS Set
dscp ef
Packets marked 0
Class-map: class-default (match-any)
1 packets, 60 bytes
30 second offered rate 0000 bps, drop rate 0000 bps
Match: any
c2921#sh int g0/0 | i pack
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
102 packets input, 12332 bytes, 0 no buffer
102 packets output, 11520 bytes, 0 underruns
c2921#
These packet link type is LINK_IEEE_SPANNING ( 19 ).
can you explain how its happening like this? Why the counters not getting incremented in policy attached in g0/0?
