NCS4K-24LR-O-S line card has maximum 40G capacity. There are four10G port and 20 low rate ports. Since at a time we cannot use all ports below are few combinations which can be used:
-
On ports 0 to 3, OC3/OC12 can be allocated only if 10GE/OC192 traffic is not configured on Port 22; on port 4 OC3/OC12 can be allocated only if OC48 is not configured on port 0; on port 22 OC3/OC12 can be allocated only if OC48 is not configured on port 2.
-
On ports 6 to 9, OC3/OC12 can be allocated only if 10GE/OC192 traffic is not configured on Port 10; on port 5 OC3/OC12 can be allocated only if OC48 is not configured on port 6; on port 10 OC3/OC12 can be allocated only if OC48 is not configured on port 8.
-
On ports 12 to15, OC3/OC12 can be allocated only if 10GE/OC192 traffic is not configured on Port 23; on port 16 OC3/OC12 can be allocated only if OC48 is not configured on port 12; on port 23 OC3/OC12 can be allocated only if OC48 is not configured on port 14.
-
On ports 18 to 21, OC3/OC12 can be allocated only if 10GE/OC192 traffic is not configured on Port 11; on port 17 OC3/OC12 can be allocated only if OC48 is not configured on port 18; on port 11 OC3/OC12 can be allocated only if OC48 is not configured on port 20.
