LACP between Nexus 5K and Netscaler

[ptoomath01]

We are attempting to migrate a Netscaler 8200 from a Catalyst 6500 to Nexus 5672's. I've copied the LACP config across (4 x 1Gbps links) but when connected to the Nexus the Netscaler LACP link shows as "Partial-up" but when connected to the 6500 it shows as "up".

Everything looks fine on the Nexus, and traffic is working but we had to back-out because of the status on the Netscaler.

Any help appreciated.

Is the Netscaler connected to 2 5ks?

if yes, are the uplinks in a VPC?

Can you post configs from both 5ks?

Hi Reza,

No vpc, just 4 ports from the Netscaler to the same 5K. config below;

interface port-channel59
  description NETSCALAR XXX - Local ports Eth1/25-28 
  switchport access vlan 140
  speed 1000
  duplex full

interface Ethernet1/25
  description NETSCALER XXX NIC1 - (Port-Chan 59)
  switchport access vlan 140
  speed 1000
  duplex full
  channel-group 59 mode active

interface Ethernet1/26
  description NETSCALER XXX NIC2 - (Port-Chan 59)
  switchport access vlan 140
  speed 1000
  duplex full
  channel-group 59 mode active

interface Ethernet1/27
  description NETSCALER XXX NIC3 - (Port-Chan 59)
  switchport access vlan 140
  speed 1000
  duplex full

Hi,

Config looks good.

What is the output of "sh ether-ch summ"?

[ptoomath01]

That looks good too...

Everything on the Nexus looks fine it is just the Netscaler that shows "Partial-up" that is the problem (it was OK when connected to the 6509)
