  • show wccp cache—Displays WCCP cache engine information.

  • show wccp flows—Displays WCCP packet flows.

  • show wccp routers—Displays the WCCP router list.

  • show wccp services—Displays the WCCP services that are configured.

  • show wccp slowstart—Displays the WCCP slow start.

Command Summary

These are the cache engine commands that were used in this configuration:

  • wccp version {1 | 2}

  • wccp router-list number ip-address
