long-distance-isl
2
The following displays the port groups and number of port groups available on each platform for
long distance Metro VCS.
*Not a valid deployment scenario at distances longer than 5 km, as no
normal ISLs are allowed if both port-groups are configured with
long-distance ISLs for 10 km and 30 km.For a 10 km ISL link, no other
ISL links are allowed on the same ASIC.
For 2 km and 5 km ISL links, another short distance ISL link can be configured.
A maximum of three PFCs can be supported on a long distance ISL link.
Enter no long-distance-isl to revert to the default value.
Examples To extend the support of an ISL port with PFC by a distance of 5 km on a specific 10-gigabit
Ethernet interface:
switch(config)# interface tengigabitethernet 178/0/9
switch(conf-if-te-178/0/9)# long-distance-isl 5000
