Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

This command is supported only on switches configured with the Supervisor Engine 1 with Layer 3 Switching Engine WS-F6K-PFC (Policy Feature Card).

Entering the destination keyword specifies the entries matching the destination IP address specification, entering the source keyword specifies the entries matching the source IP address specification, and entering an ip_addr_spec can specify a full IP address or a subnet address. If you do not specify a keyword, it is treated as a wildcard, and all entries are displayed.

When entering the ip_addr_spec, use the full IP address or a subnet address in one of the following formats: ip_addr, ip_addr/netmask, or ip_addr/maskbit.

If you do not enter any keywords, the LD is removed from the switch, and the LD configuration is removed from NVRAM.

If you do not enter any keywords with the clear lda mls command, all ASLB MLS entries are cleared.

Examples

This example shows how to clear the ASLB MLS entry at a specific destination address:

Console> (enable) clear lda mls destination 172.20.26.22

MLS IP entry cleared.

Console> (enable)

clear mls entry ip destination ip_addr_spec [source ip_addr_spec] [protocol protocol] [src-port src_port] [dst-port dst_port]

clear mls entry ipx destination ipx_addr_spec

Syntax Description

ip	(Optional) Specifies IP MLS.
ipx	(Optional) Specifies IPX MLS.
all	Clears all MLS entries.
destination	Specifies the destination IP address.
ip_addr_spec	Full IP address or a subnet address in these formats: ip_addr, ip_addr/netmask, or ip_addr/maskbit.
source ip_addr_spec	(Optional) Specifies the source IP address.
protocol protocol	(Optional) Specifies additional flow information (protocol family and protocol port pair) to be matched; valid values are 0 to 255 or ip, ipinip, icmp, igmp, tcp, and udp.
src-port src_port	(Optional) Specifies the source port IP address; valid values are 1 to 65535, dns, ftp, smtp, telnet, x (X-Windows), www.
dst-port dst_port	(Optional) Specifies the destination port IP address; valid values are 1 to 65535, dns, ftp, smtp, telnet, x (X-Windows), www.
ipx_addr_spec	Full IPX address or a subnet address in these formats: src_net/[mask], dest_net.dest_node, or dest_net/mask.

Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

This command is not supported on systems configured with the Supervisor Engine 2 with Layer 3 Switching Engine II (PFC2). To clear entries on systems configured with the Supervisor Engine 2 with Layer 3 Switching Engine II (PFC2), you must enter the clear mls entry cef command.

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

•IPX net 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 6500 series switches.

•The Catalyst 6500 series 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 in the clear mls entry command, you must specify at least one of the other three keywords (source, destination, or protocol) and its arguments.

If no value or 0 is entered for src_port and dest_port, all entries are cleared.

When you remove a Multilayer Switch Module (MSM) from the Catalyst 6500 series switch, it is removed immediately from the inclusion list and all the MLS entries for the MSM are removed.

Examples

This example shows how to clear the MLS entries with destination IP address 172.20.26.22:

Console> (enable) clear mls entry destination 172.20.26.22 

Multilayer switching entry cleared.

Console> (enable)

This example shows how to clear specific IP MLS entries for destination IP address 172.20.26.22:
