Hi All,
I have a question,
I want to give Cos 5 vlaue the highest priority and bandwidth when
traversing L-2 Trunk, as this is not the voice traffic and i m marking the
traffic coming from servers to 5 and then on the trunk link between two
switches, i want to put the cos 5 to the output priority queue.
Sw1--->Sw2
Actually these are the blade switches
Sw1 and 2 have L-2 trunk between them and have servers connected to them on
fastethernet ports.
i have configured as following :-
Sw1
-----
mls qos srr-queue output cos-map queue 4 5 (5 being the cos map and 4
being the queue-id assuming the priority queue is number 4)
mls qos srr-queue output 1 buffers 10 10 10 70 (4th queue given higher
buffer allocation)
int gi0/1
switchport mode trunk
switchport trunk encapsulation dot1q
priority-queue out
queue-set 1
SW2
------
mls qos srr-queue output cos-map queue 4 5 (5 being the cos map and 4 being
the queue-id assuming the priority queue is number 4)
mls qos srr-queue output 1 buffers 10 10 10 70 (4th queue given higher
buffer allocation assuming the priority queue is number 4)
int gi0/1
switchport mode trunk
switchport trunk encapsulation dot1q
priority-queue out
queue-set 1
on server side interfaces on the same switches :-
int f0/1
switch mode access
switch acc vlan 5
mls qos cos 5
mls qos cos override
I want to be sure that is this the way we assign priority to the traffic we
want; or is ther any other way to achieve this.
one more question which queue will become the priority queue when
"priority-queue out" is configured as it is not mentioned in the DOC cd.
Thanks in advance.
Jatin.
