[f-nsp] keep-alive over active/active link

Hi

I have the current setup in an active/active configuration:

||========CORE=======||
||                                           ||
Serveriron00==///==Serveriron01

The link between the two serverirons (running switch code base
09.5.02mTF3) is on a separate VLAN with no kind of STP enabled and is
a trunk made up of two physical ethernet links, 2/5 and 2/6 with 2/5
being the primary trunk port.

Below is a snippet of the configuration.

Serveriron00

<snip>
!
trunk switch ethe 2/1 to 2/4
 config-trunk-ind
 monitor ethe-port-monitored 2/1 ethe 2/7 both
 monitor ethe-port-monitored 2/2 ethe 2/7 both
 monitor ethe-port-monitored 2/3 ethe 2/7 both
 monitor ethe-port-monitored 2/4 ethe 2/7 both
trunk switch ethe 2/5 to 2/6
 config-trunk-ind

Serveriron00#sh vlan 200
Total PORT-VLAN entries: 2
Maximum PORT-VLAN entries: 32

PORT-VLAN 200, Name ACTIVE-ACTIVE, Priority level0, Spanning tree Off
 Untagged Ports: (S2)  5  6
   Tagged Ports: None
   Uplink Ports: None
 DualMode Ports: None

Serveriron01#sh vlan 200
Total PORT-VLAN entries: 2
Maximum PORT-VLAN entries: 32

PORT-VLAN 200, Name ACTIVE-ACTIVE, Priority level0, Spanning tree Off
 Untagged Ports: (S2)  5  6
   Tagged Ports: None
   Uplink Ports: None
 DualMode Ports: None

In order to have keep-alives purely over that trunk as opposed to
going through the CORE, would I enter the following on _both_
Serverirons?

(config)#link-keepalive ethernet 2/5 ethernet 2/6

The documentation of the code base I am running is a little sparse and
all I can find on this is in the document "Foundry Switch and Router
Installation and Basic Configuration Guide" where it talks about
configuring UDLD. Apologies, but I am a little confused.
