Hi,
In one of he practice lab scenarios, CBWFQ was asked to be
configured on a serail link (256 Kbps) to allocate bandwidth to various
protocols.
The total allocation came to 203 Kbps. In addition to it, strict priority of
48 Kbps was reserved for voice traffic (using rtp priority command)
The solution provided was as follows. Here max-reserved-bandwidth was
configured as 80% for the serail link. The total bandwidth reserved is 203 +
48 = 251 Kbps,
which is close to 99%(of 256 Kbps). Hence i think the max-reserved-bandwidth
should be 99%, right ? Pls let me know.
