Filters

5-9

• Pseudo – allows you to create a pseudo filter to monitor traffic

patterns without discarding packets.

• And/Or – allows you to combine multiple port filters using the

and/or operators to create boolean ﬁlter expressions.

These options are discussed in detail in the section “Combination

port ﬁlter options”.

When you are adding ﬁlters, you are prompted for all of the

possible ﬁeld value options. The prompt usually includes a default

value in brackets that will be used if you don’t specify a value.

Conﬁgurable ﬁelds are described in the sections that follow.

Type

Either Entry (apply the ﬁlter to all packets received on the port) or

Exit (apply the filter before transmitting the packet from the port).

Entry is the default.

Note: Use PMEntry and PMExit to filter when using the port mirroring

option.

Source Range

Either NA (not applicable), True (ﬁlter the packet if the source

MAC address is within the range), or False (ﬁlter the packet if the

source MAC address is outside of the range). NA is the default.

Source Range Start

The starting MAC address for the source range of MAC addresses.

Source Range End

Ending MAC address for the source range of MAC addresses. If

you are ﬁltering on a single address, no entry is required.
