show mac

Use the show mac command to display MAC counters.

Syntax Description

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 module

Use the show module command to display module status and information.

Syntax Description

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.

For Catalyst 4000 series switches, in the show module command display, the combination of the 32-port module (WS-X4502) and 4-port 100FX daughtercard results in an entry that reads 36 ports. If the uplink daughtercard is not installed, only ports 1 through 32 are listed.

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. Both 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 and 2926G series switches):

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

The igmp keyword is not supported by the Catalyst 4000 and 2948G series switches.

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.

show port

Use the show port command to display port status and counters.

Syntax Description

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

In the status field for the Catalyst 5000, 4000, 2948G, and 2926G series switch ports, the following applies:

• connected indicates the port is operational.

---

Note connected is also displayed for the status of a port that is receiving remote fault indications. Remote fault indications are not sent until the link comes up and both ends can hear each other. By definition, this means the link is up and everthing is working correctly. According to the 802.3z Gigabit Ethernet Spec, a link partner is not allowed to send remote fault indications until after the link comes up successfully.

---

• 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.

For Catalyst 4000 series switches, in the show port command display, the combination of the 32-port module (WS-X4502) and 4-port 100FX daughtercard results in a entry that reads 36 ports. If the uplink daughtercard is not installed, only ports 1 through 32 are listed.

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 and 2926G series switches):

Table 2-51 describes the possible fields (depending on the port type queried) in the show port command output.

Table 2-51: show port Command Output Fields

Field	Description
Port	Module and port number.
Name	Name (if configured) of the port.
Status	Status of the port. For the Catalyst 5000 and 2926G series switches, possible displays are connected, notconnect, connecting, standby, faulty, inactive, shutdown, disabled, or monitor; for the Catalyst 4000 and 2948G series switches, possible displays are connected, notconnected, faulty, remfault, disable, remdisable, configerr, remcfgerr, and disagree.
Vlan	VLANs to which the port belongs.
Duplex	Duplex setting for the port (auto, full, fdx, half, hdx, a-half, a-hdx, a-full, or a-fdx).
Speed	Speed setting for the port (auto, 10, 100, 155, a-10, a-100, 4, 16, a-14,or a-16).
Type1	Port type, for example, 100BaseFX MM, 100BaseFX SM, 10/100BaseTX, or RSM.
Security	Status of whether port security is enabled or disabled.
Secure-Src-Addr	Secure MAC address for the security enabled port.
Last-Src-Addr	Source MAC address of the last packet received by the port.
Shutdown	Status of whether the port was shut down because of security.
Trap	Status of whether port trap is enabled or disabled.
IfIndex	Number of the ifIndex.
Broadcast-Limit	Broadcast threshold configured for the port.
Broadcast-Drop	Number of broadcast/multicast packets dropped because the broadcast limit for the port was exceeded.
Send admin	Flow-control administration. Possible settings: on indicates the local port sends flow control to the far end; off indicates the local port does not send flow control to the far end; desired indicates the local end sends flow control to the far end if the far end supports it.
FlowControl oper	Flow-control operation. Possible setting: disagree indicates the two ports could not agree on a link protocol.
Receive admin	Flow-control administration. Possible settings: on indicates the local port requires the far end to send flow control; off indicates the local port does not allow the far end to send flow control; desired indicates the local end allows the far end to send flow control.
FlowControl oper	Flow-control operation. Possible setting: disagree indicates the two ports could not agree on a link protocol.
RxPause	Number of Pause frames received.
TxPause	Number of Pause frames transmitted.
Unsupported Opcodes	Number of unsupported operating codes.
Align-Err	Number of frames with alignment errors (frames that do not end with an even number of octets and have a bad CRC) received on the port.
FCS-Err	The number of valid size frames with FCS error sbut no framing errors.
Xmit-Err	Number of transmit errors that occurred on the port (indicating that the internal transmit buffer is full).
Rcv-Err	Number of receive errors that occurred on the port (indicating that the internal receive buffer is full).
UnderSize	Number of received frames less than 64 octets long (but are otherwise well-formed).
Single-Coll	Number of times one collision occurred before the port transmitted a frame to the media successfully.
Multi-Coll	Number of times multiple collisions occurred before the port transmitted a frame to the media successfully.
Late-Coll	Number of late collisions (collisions outside the collision domain).
Excess-Col	Number of excessive collisions that occurred on the port (indicating that a frame encountered 16 collisions and was discarded).
Carri-Sen	Number of times the port sensed a carrier (to determine whether the cable is currently being used).
Runts	Number of received runt frames (frames that are smaller than the minimum IEEE 802.3 frame size) on the port.
Giants	Number of received giant frames (frames that exceed the maximum IEEE 802.3 frame size) on the port.
Last-Time-Cleared	Last time the port counters were cleared.
Auto-Part	The number of times the port entered the auto-partition state due to excessive consecutive collisions.
Data-rate mismatch	The number of valid size frames experienced overrun or underrun.
Src-addr change	The number of times the last source address changed.
Good-bytes	The total number of octets in frames with no error.
Short-event	The number of times activity with a duration less than the ShortEventMax Time (74-82 bit times) is dectected.

1These fields will change according to the system configuration.
