Figure 9-1 CoS Functional Model
The 9145ELB has a set of egress queues assigned to each port. Each User Port has a set of
four egress queues, labelled from highest to lowest priority as LLQ, Q3, Q2, Q1, respectively.
This will also include port 10G2 if it is configured as a User Port (see the section “Port Config/
Status Screens” on page 59).
The Network Port can have a different set of egress queues, based on whether 10G2 is
configured to be Disabled, a Network Port or a User Port:
Figure 9-2 shows a system-level logical view of the queue assignment.
If 10G2 is Disabled
Network Port 10G1 has 19 egress queues in total: 1 dedi-
cated LLQ for each User Port and 3 additional queues that
are shared across all User Ports
If 10G2 is set to Network Port *
Network Port 10G2 has 19 egress queues in total: 1 dedi-
cated LLQ for each User Port and 3 additional queues that
are shared across all User Ports.
If 10G2 is set to User Port
Network Port 10G1 has 12 egress queues in total: 1 dedi-
cated LLQ for each User Port and 3 additional queues that
are shared across all User Ports.
* Note that if 10G2 is set to Network Port, then 10G1 must be Disabled
