cisco C6807-XL don't support bfd interval menor to 750

[csco11665954]

Hi all,

I have 6807 that not support bfd interval menor to 750 in interface.

someone can say me if next configuration with bfd template will work:

( I can't test in production 6807)

Device> enable
Device# configuration terminal
Device(config)# bfd-template single-hop template1
Device(bfd-config)#interval min-tx 50 min-rx 50 multiplier 3
Device(bfd-config)#echo
...
Device> enable
Device# configuration terminal
Device(config)# interface Gigabitethernet 1/3/0
Device(config-if)# bfd template template1

Are you referring to this? 

Cisco Catalyst 6000 Series Switches
• In the Cisco Catalyst 6000 series switches, the supervisor uplink ports have to be associated with the
BFD timer value of 750*750*5 milliseconds because during the stateful switchover (SSO) or peer reload,
the redundancy facility (RF) progression and EtherChannel (port-channel) load calculation takes 1.5 to
2.5 seconds. This is applicable even if the BFD echo packets are exchanged over the supervisor uplinks

As per the documentation, the 750 is required on suppervisor uplink. As I can see on your script, Gigabitethernet 1/3/0 must be suppervisor uplink and must use 750.

Hi Flavio,

thank for you answer. 

My example was wrong, in reality what I need is to apply the command in a vlan that is in a portchannel in a module 
that is not a supervisor. Even so, it does not accept lower values.
¿ do you think the same ?

interface Vlan410
description vpn0-pu1_peer-BGP_agg-liray
ip vrf forwarding sdwan-vpn0-pu1
ip address 10.101.251.66 255.255.255.252
no ip redirects
no ip unreachables
bfd interval 750 min_rx 750 multiplier 3

this vlan go for port channel 44
