A customer has a four-port vLAG between two VDX switches and a server. Two of the four links are up but the vLAG will not come up. VDX8770_3-131# show interface po 710 Port-channel 710 is up, line protocol is down (link protocol down) Hardware is AGGREGATE, address is 0005.33d4.0d2c Current address is 0005.33d4.0d2c Interface index (ifindex) is 671089350 Minimum number of links to bring Port-channel up is 3 MTU 2500 bytes LineSpeed Actual : Nil Allowed Member Speed : 10000 Mbit Priority Tag disable IPv6 RA Guard disable Last clearing of show interface counters: 2d05h53m Queueing strategy: fifo Receive Statistics:
