Cisco 4510R-E slot capacity
Posted on 2011-10-12
I am looking for some deeper detail on slot capacity inside the 4510R-E with a Supervisor 6e, centered around the differences between classic and "E" series line card use.
Cisco states the following for E and Classic line cards:
24 gigabits per-slot capacity
Bandwidth is allocated across eight 6-port groups, providing 3 Gbps per port group (2:1)
6 gigabits per-slot capacity
Bandwidth is allocated across six 8-port groups, providing 1 Gbps per port group
I am trying to determine 2 things:
1. For the X# of port groups, providing X# Gbps per port group;
How do you determine which actual ports on the line card participate in which "port group"? It seems to me based on wording, that I may want to put a heavily congested server alone in a "port group" to guarantee the X# Gbps throughput?
2. For the X# gigabits per second slot capacity;
Is my understanding correct that this translates to say 6 or 24Gbps total output from this slot to the chassis fabric? Meaning if I had 8 1Gbps devices running full steam on a 6Gbps slot, they would oversubscribe the slot?
