Subject said it all.
I have ECLB configured on Catalyst 3850:
udld enable
udld message time 2
interface TenGigabitEthernet1/1/1
switchport trunk native vlan 4094
switchport trunk allowed vlan 1,1500,4094
switchport mode trunk
udld port aggressive
channel-group 1 mode on
interface TenGigabitEthernet2/1/1
switchport trunk native vlan 4094
switchport trunk allowed vlan 1,1500,4094
switchport mode trunk
udld port aggressive
channel-group 1 mode on
interface Port-channel1
description PORTCHANNELS TO IPS
switchport trunk native vlan 4094
switchport trunk allowed vlan 1,1500,4094
switchport mode trunk
IPS interfaces are hardcoded to 10Gb.
Whenever I reload or power cycle IPS, interface stays up entire time and doesn't get error disabled, which pretty much ends up with black holing almost entire traffic. Can anyone help me with this?
