show mls

Use the show mls command set to display MLS Layer 3 packet information in the MLS-based Catalyst 5000 series switch.

show mls
show mls rp {ip_addr} [noalias]
show mls entry {[destination {ip_addr_spec}] [source {ip_addr_spec}] | [flow {protocol} {src_port [port_num]} {dst_port}]} [rp {ip_addr}]
show mls include
show mls nde

Syntax Description


rp	Keyword to specify a route processor.
ip_addr	Route-processor IP address or route-processor name if DNS is used.
noalias	(Optional) Keyword to specify all route processors are present in IP format, rather than their names.
entry	Keyword to specify the MLS packet entry.
destination	(Optional) Keyword to specify the destination IP address.
ip_addr_spec	(Optional) Full IP address or a subnet address in the following formats: ip_subnet_addr, ip_addr/subnet_mask, ip_addr/#subnet_mask_bits.
source	(Optional) Keyword to specify the source IP address.
flow	(Optional) Keyword to specify additional flow information (protocol family and protocol port pair) to be matched.
protocol	(Optional) Keyword to specify flow information; valid values include tcp, udp, icmp, or a decimal number for other protocol families.
src_port	(Optional) Source port IP address; used with port_num to specify the port pair if protocol is tcp or udp.
port_num	(Optional) TCP/UDP port number (decimal); used with src_num to specify the port pair if protocol is tcp or udp.
dst_port	(Optional) Destination port IP address.
include	Keyword to display all route processors currently included to run MLS.
nde	Keyword to display NDE information.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

If you are entering any of the show mls commands on a Catalyst 5000 series switch without MLS, the following warning message is displayed: MLS not supported on feature card.

If you enter the show mls commands with no arguments, general MLS information and all MLS-RP information are displayed.

If DNS is disabled, no name can be specified or shown. If noalias is specified, all route-processors are presented in IP format, if DNS is enabled.

A value 0 for src_port and dst_port means "don't care."

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 with a length 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 allowed to be 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 allowed to be a full host address, such as 172.22.254.1/22, which has the same subnet address as 172.22.252.00/72.

When you enter the show mls entry command, the keyword destination option specifies the entries matching this destination IP address specification. The keyword source option specifies the entries matching this source IP address specification. An ip_addr_spec can be 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.
