You could use rsvp to reserve bandwidth, and I believe that policy maps will
also accomplish this. Assuming that you are not given a packet size, the
configuration you have should service the default 1500 bytes from each of
the 2 queues, thereby giving you 50/50 bandwidth distribution give or take.
If you are given packet sizes there are a few calculations that you will
have to go through. I think you have a typo in that access list, it should
be 2065 not 2062. Also, remember that the lower ip address in the dlsw
peering will transmit using source port 2065, if you want to have a blanket
list for queueing that would take into account whether the transmitted
packets are from the higher or lower ip address then you would have to have
an access list like this. This access list should queue any dlsw packets
that go through the interface regardless of whether they are from the higher
or lower ip address. At least that is my opinion, other people have
different methods, but I am pretty sure this list would queue any dlsw
packets. Does anyone care to comment, I would like to hear other opinions.
access 101 permit tcp any eq 2065 any (source port of 2065 to any
destination port)
access 101 permit tcp any any eq 2065 (any source port to destination
port 2065)
access 101 permit tcp any eq 1981 any
access 101 permit tcp any any eq 1981
access 101 permit tcp any eq 1982 any
access 101 permit tcp any any eq 1982
access 101 permit tcp any eq 1983 any
access 101 permit tcp any any eq 1983
access 101 permit udp any eq 0 any eq 2067 (for explorer traffic)
access 101 permit udp any eq 2067 any eq 0 (for explorer traffic)

~
~
~Hi Group
~
~
~As per this url under Custome Queuing section
~
~http://www.cisco.com/warp/public/cc/pd/ibsw/ibdlsw/prodlit/dlsw5_rg.htm
~
~Custom queuing reserves a portion of the bandwidth of
~a link for each selected traffic type
~
~could someone please tell me if both configs below
~would reserve 50% of bandwidth for dlsw .
~
~
~queue-list 1 protocol ip 1 tcp 2065
~queue-list 1 default 2
~
~
~OR
~
~queue-list 1 protocol ip 1 list 101
~queue-list 1 default 2
~
~Access-list 101 permit tcp any eq 2062 any
~Access-list 101 permit tcp any any eq 1981
~Access-list 101 permit tcp any any eq 1982
~Access-list 101 permit tcp any any eq 1983
~
~Apart from using CQ, is there any other way to reserve
~bandwidth for dlsw ?
~
~
~Any feedback is greatly appreciated
~
~CL
