Usage Guidelines
You can specify the core filter as a class map, access list, or an explicit in-line filter. If the filter has
already been specified when you enter this command, it replaces the older one.
The explicit, in-line filter is intended as a simple way to specify a core filter. In certain situations, you
must go through the approval process to change a configuration, which could be time-consuming.
Although explicit filters simplify this process, be aware that support is more extensive for access list and
class maps.
You can capture IPv4, IPv6, MAC, or "any" traffic by specifying the appropriate keywords. Depending
on the traffic type, the usage varies. For a MAC, you can specify an address or prefix. For IPv4 or IPv6,
you can match on several fields. For source or destination ports, several operators are supported.
Examples
The following example usages show how to set or remove an explicit filter:
Switch# monitor capture mycap match any
Switch# monitor capture mycap match mac any any
Switch# monitor capture mycap match mac host 0000.0a01.0102 host 0000.0a01.0103
Switch# monitor capture mycap match ipv4 any any
Switch# monitor capture mycap match ipv4 host 10.1.1.2 host 20.1.1.2
