Troubleshooting CoS Schedulers on a 40-port SFP+ Line Card in an EX8200 Switch
This topic provides troubleshooting information for specific problems related to
class-of-service (CoS) schedulers on a 40-port SFP+ line card in an EX8200 Switch.

Problem
The default scheduler map associated with a few ports in a port group in a 40-port SFP+
line card in an EX8200 switch is replaced with a configured scheduler map.
Cause
The ports in a 40-port SFP+ line card are divided into eight groups, each group comprising
five ports. The ports in a port group share 10 gigabits of bandwidth. Because the port
groups share bandwidth, CoS ingress and egress queues are handled differently on the
40-port SFP+ line card than on other line cards for EX8200 switches. Only one scheduler
map can be active at a time in a port group.
In a port group, if you install transceivers in a port on which you have configured a scheduler
map and in a port associated with the default scheduler map, the scheduler maps on all
ports in that port group are replaced with the scheduler map you configured. For example,
if you configure scheduler map M1 on port 0 and install transceivers in that port and in
any other port in port group 0 (see Figure 82 on page 3236), the scheduler maps on all ports
in that port group are replaced with the scheduler map M1.
