How to configure?
1. Define one event list. The prerequisite of event trigger is that
interface gei_1/1 is down;
2. Define one standard ACL, where rule 1 permits all packets to
pass through, rule 2 denies all packets. By associating rule 1
with event, execute rule 1 when protocol on interface gei_1/1
is down;
3. Apply ACL on “in” direction of interface gei_1/2.
Configuration of Switch C:
ZXR10(config)#event-list zte
ZXR10(config-event)#interface gei_1/1 protocol down
ZXR10(config-event)#exit
ZXR10(config)#acl standard number 1
ZXR10(config-std-acl)#rule 1 permit any event zte
ZXR10(config-std-acl)#rule 2 deny any
ZXR10(config-std-acl)#exit
ZXR10(config)#interface gei_1/2
ZXR10(config-if)#ip access-group 1 in
When protocol on gei_1/1 is down, rule 1 becomes effective. Traf-
fic can access gei_1/2. When protocol on gei_1/1 is up, rule 1 is
not effective. Traffic fails to access gei_1/2 and can only access
interface gei_1/1. In above cases, there is only one data flow can
be received on SwitchC.
