Avaya G450 Port Redundancy

[techyboy14]

Hi all, we had an issue with one of our Avaya G450 gateway configured with port redundancy on port 5 and 6 connecting to two different CISCO switches which seemed to have flooded our network with broadcast when plugged in. We did plug both ports from the gateway to the switches at the same time after the G450 was configured (not sure if that makes a difference)

is it necessary to run the "set port redundancy enable" command after setting "set port redundancy 10/5 10/6 on "Monitor"?
here is the config:

hostname "GATEWAY05"
no ip telnet
set port redundancy 10/5 10/6 on "Monitor"
set spantree disable
