Re: Class Default

There is an implied class-default attached to a policy-map when you attach
it to an interface even if you don't specifically assign it.

R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#class-map voice
R1(config-cmap)#match dscp ef
R1(config-cmap)#exit
R1(config)#policy-map LLQ
R1(config-pmap)#class voice
R1(config-pmap-c)#priority 83
R1(config-pmap-c)#^Z
R1#
*Aug 7 10:28:35.255: %SYS-5-CONFIG_I: Configured from console by console
R1#show policy-map
  Policy Map LLQ
    Class voice
      priority 83 (kbps)

R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int fa0/0
R1(config-if)#service-policy output LLQ
R1(config-if)#^Z
*Aug 7 10:29:18.587: %SYS-5-CONFIG_I: Configured from console by console
R1#show policy-map int fa0/0
 FastEthernet0/0

  Service-policy output: LLQ

    queue stats for all priority classes:

      queue limit 64 packets
      (queue depth/total drops/no-buffer drops) 0/0/0
      (pkts output/bytes output) 0/0

    Class-map: voice (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: dscp ef (46)
      Priority: 83 kbps, burst bytes 2050, b/w exceed drops: 0

    Class-map: class-default (match-any)
      7 packets, 1458 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: any

      queue limit 64 packets
      (queue depth/total drops/no-buffer drops) 0/0/0
      (pkts output/bytes output) 4/314
R1#
