Question. If you do not specify the "class-default" class in a policy-map,
the class-default class appears, but it does not say "Weighted fair
queueing". Can someone tell me what it IS doing?
ex:
class-map match-all Prec-5
match ip precedence 5
policy-map GAD
class Prec-5
bandwidth percent 90
int s0
service-policy outbound GAD
R3#sho policy-map interface s0
Serial0
Service-policy output: GAD
Class-map: Telnet (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: ip precedence 5
Weighted Fair Queueing
Output Queue: Conversation 265
Bandwidth 90 (%) Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
Class-map: class-default (match-any)
1 packets, 13 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
Difference when you add:
class class-default
bandwidth percent 10
To the policy map is:
R3#sho policy-map interface s0
Serial0
Service-policy output: GAD
Class-map: Telnet (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: ip precedence 5
Weighted Fair Queueing
Output Queue: Conversation 265
Bandwidth 90 (%) Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
Class-map: class-default (match-any)
38 packets, 494 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
Weighted Fair Queueing
Output Queue: Conversation 266
Bandwidth 10 (%) Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
Notice the addition of the last 5 lines.
So my question is, in the first example, what is the queuing mechaninsm if
not WFQ? Queueing for the interface is Weighted Fair as shown in in a show
int:
Serial0 is up, line protocol is up

0 output errors, 0 collisions, 3 interface resets
0 output buffer failures, 0 output buffers swapped out
1 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
I'm sure the answer is obvious somehwere, but I'm fried and it's eluding
me.
Thanks!
