i've installed a new 10GE PIC ( PC-1XE-TYPE3-XFP-IQ2) on M320 FPC (M320-FPC3-E3).
and i'm using class of service on this interface, with a schedular-map of 4 schedulers, 2 of them with priority: high, and the other 2 with priority: low
when checking the config. (by commit check), i recieved this error:
More than one scheduler is configured as "strict-high" or "high" or "medium-high" in SCHEDULER_MAP for xe-2/0/0. Ifd xe-2/0/0 supports only one scheduler with "strict-high" or "high" or "medium-high".
error: configuration check-out failed
So Is this a hardware limitation and can't be changed? or i can modfiy something in the interface config. to make it accept this CoS mapping?
Also Is increasing the number of egress queues of this interface (from 4 to 8) can solve this issue?
Thanks in advance.

This is HW limitation and it is well documented. It was first documented when IQ2 PICs were released
Note: Gigabit Ethernet IQ2 PICs support only one queue in the scheduler map with high or strict-high priority
You need IQE PIC to support >1 high/strict-high queue
