ACE Primary/Failover Throughput

[robert.horrigan]

Hi,

Is it possible to get 4Gb throughput on an HA setup?  I know I can get ~3Gb throughput by channeling three uplinks to the upstream switch.  I understand that the fourth uplink needs to crossconnect to the other ACE for the FT interface.  Is it possible to channel all four interfaces and use the channel as the FT interface as well as for data?

No you don't need a direct cross connect, here is my typical configuration sample :

peer hostname ACE-S2
hostname ACE-S1
shared-vlan-hostid 1
peer shared-vlan-hostid 2
interface gigabitEthernet 1/1
  channel-group 1
  no shutdown
interface gigabitEthernet 1/2
  channel-group 1
  no shutdown
interface gigabitEthernet 1/3
  channel-group 1
  no shutdown
interface gigabitEthernet 1/4
  channel-group 1
  no shutdown
interface port-channel 1
  switchport trunk allowed vlan 5-6,21,30
  port-channel load-balance src-dst-port
  no shutdown

with 30 as the "ft interface vlan"
