show mac

Use the show mac command to display MAC counters.

show mac [mod_num[/port_num]]

Syntax Description

mod_num	(Optional) Number of the module. If you do not specify a number, all modules are shown.
/port_num	(Optional) Number of the port on the module. If you do not specify a number, all ports are shown.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guideline

If you are using a Catalyst 2948G series switch, the Catalyst 2948G is a fixed configuration switch. All ports are located on module 2; for this reason, if you enter mod_num 1/N, an error message will be displayed.

Example

This example shows how to display MAC information for port 3 on module 4:

show mls

Use the show mls command set to display MLS Layer 3 packet information in the MLS-based Catalyst 5000, 2926G, and 2926 series switches.

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, instead of 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

This command is not supported on the Catalyst 4000 and 2948G series switches.

If you are entering any of the show mls commands on Catalyst 5000, 2926G, and 2926 series switches 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 and DNS is enabled, all route-processors are presented in IP format.

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.

show module [mod_num]

Syntax Description

mod_num

(Optional) Number of the module. If you do not specify a number, all modules are shown.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

If you remove a module and replace it with a different type module, a message appears in the show module display that states that the module configuration is inconsistent with the current module type. To clear the message, you can either enter the clear config mod_num command for the module or set different parameters for the new module.

For Supervisor Engine III modules, the show module command displays the supervisor engine's module number but appends the uplink daughtercard's module type and information.

For Catalyst 4000 series switches, the show module command displays the supervisor engine as having "1" slot.

Although me1 resides on the supervisor engine module for the Catalyst 4000 and 2948G series switches, me1 port information is not displayed by the show module or show port CLI commands.

For Catalyst 2948G series switches, the show module command displays two modules, a Switching Supervisor and an Ethernet module. The output implies modularity, but the modules are internal to the box and are not removable. The show module command also displays both modules as having "1" slot.

Examples

This example shows how to display status and information for all modules on the switch (Catalyst 5000, 2926G, and 2926 series switches):

Usage Guidelines

In the status field for a Catalyst 4000 and 2948G series switch port, the following applies:

•connected indicates the port is operational.

•notconnected indicates the port is off or there is no GBIC in port.

•faulty indicates the port failed diagnostics tests.

•remfault indicates the far end station cannot synchronize with its receive signal.

•disable indicates the port has been manually disabled.

•remdisable indicates the far end port has been manually disabled.

•configerr indicates that this port is not satisfied with the output of flow control and or duplex negotiation.

•remcfgerr indicates that the far end port is not satisfied with the output of flow control and or duplex negotiation.

•disagree indicates the condition when the two ports have failed to agree on a duplex condition or when autonegotiation has failed.

Although me1 resides on the supervisor engine module for the Catalyst 4000 and 2948G series switches, me1 port information is not displayed by the show module or show port CLI commands.

The Catalyst 2948G is a fixed configuration switch. All ports are located on module 2; for this reason, if you enter mod_num/port_num 1/N, an error message will be displayed.

This example shows how to display the status and counters for port 1 on module 3 (Catalyst 5000, 2926G, and 2926 series switches):
