Hi Guys,
Just testing an ASR1000 ->2960 portchan w/ test subint on asr and vlan int on 2960 in same vlan, and Im unable to pass any packets with my "usual" config (7200->2960)...portchan comes up, and I see 2960 mac, but cannot ping. If I change the setup to use physical Int (i.e. gie1/0/0 as trunk, then gi1/0/0.88 as subint) it works fine?
i.e. not working:
ASR

Is there something different needed on the ASR for this setup, or am I seeing a potential bug?
Using the following XE on the ASR: System image file is "bootflash:/asr1000rp1-adventerprisek9.02.01.01.122-33.XNA1.bin"
Cheers.

Hi - just to reply to my own post, found the following link http://www.cisco.com/en/US/docs/ios/lanswitch/configuration/guide/lsw_cfg_gecvlan_ps9587_TSD_Products_Configuration_Guide_Chapter.html
Which works:
Router#ping 10.10.10.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.10.2, timeout is 2 seconds:

Router#sh etherchannel load-balancing
EtherChannel Load-Balancing Method:
vlan-manual
but I would prefer load-balancing over the 2 portchan members to be automatic, not have to config them on a per-vlan basis?
