source ipx_network	(Optional) Keyword and variable to specify the source IPX address. See the "Usage Guidelines" section for formatting guidelines.

Defaults

This command has no default setting.

Command Modes

Privileged EXEC mode.

Usage Guidelines

Entering any combination of input parameters will narrow down the search of entries to be cleared. Source_port and destination_port should be specified as one of the following: telnet, FTP, WWW, SMTP, X, or DNS.

When entering the IPX address syntax, use the following format:

• IPX network address---1..FFFFFFFE

• IPX node address---x.x.x where x is 0..FFFF

• IPX address---ipx_net.ipx_node (for example 3.0034.1245.AB45, A43.0000.0000.0001)

Up to 16 routers can be included explicitly as MLS-RPs.

To use a router as an MLS, you must meet these conditions:

• The router must be included (either explicitly or automatically) in the MLS-SE.

• The MLS feature must be enabled in the Catalyst 6000 family switches.

• The Catalyst 6000 family switches must know the router's MAC-VLAN pairs.

Use the following syntax to specify an IP subnet address:

• ip_subnet_addr---This is the short subnet address format. The trailing decimal number 00 in an IP address YY.YY.YY.00 specifies the boundary for an IP subnet address. For example, 172.22.36.00 indicates a 24-bit subnet address (subnet mask 172.22.36.00/255.255.255.0), and 173.24.00.00 indicates a 16-bit subnet address (subnet mask 173.24.00.00/255.255.0.0). However, this format can identify only a subnet address of 8, 16, or 24 bits.

• ip_addr/subnet_mask---This is the long subnet address format. For example, 172.22.252.00/255.255.252.00 indicates a 22-bit subnet address. This format can specify a subnet address of any bit number. To provide more flexibility, the ip_addr is a full host address, such as 172.22.253.1/255.255.252.00.

• ip_addr/maskbits---This is the simplified long subnet address format. The mask bits specify the number of bits of the network masks. For example, 172.22.252.00/22 indicates a 22-bit subnet address. The ip_addr is a full host address, such as 193.22.253.1/22, which has the same subnet address as the ip_subnet_addr.

If you do not use the all argument, you must specify at least one of the other four keywords (source, destination, flow, or interface) and its arguments.

A 0 value for src_port and dst_port clears all entries. Unspecified options are treated as wildcards, and all entries are cleared.

Examples

This example shows how to clear all entries associated with specific interface (e2/2) that have a specific destination IP address (173.11.50.89):

Router# clear mls ip destination 173.11.50.89 interface e2/2
Router#

clear mls exclude protocol

Use the clear mls exclude protocol command to remove an MLSE entry.

Syntax Description

tcp	Keyword to specify a TCP port.
udp	Keyword to specify a UDP port.
all	Keyword to specify that the port be applied to both TCP and UDP traffic.
port port_number	(Optional) Keyword and variable to specify the number of the port.

Defaults

This command has no default setting.

Command Modes

Privileged EXEC mode.

Examples

This example shows how to set TCP packets in a protocol port to be hardware switched:

Router# clear mls exclude protocol tcp 25
Router#

clear mls ip multicast statistics

Defaults

This command has no default setting.

Router# clear mls nde flow exclude
Router#
