Format: show mac-addr-table [{<macaddr> <vlan_id> | all | count | interface <unit/slot/port> | vlan <vlan_id>}]
Mode: Privileged EXEC
The following information displays if you do not enter a parameter, the keyword all, or the MAC address and VLAN ID. If you enter vlan <vlan_id>, only the Mac Address, Interface, and Status fields appear.
Mac Address: A unicast MAC address for which the switch has forwarding and or filtering information. The format is 6 or 8 two-digit hexadecimal numbers that are sep arated by colons, for example 01:23:45:67:89:AB. In an IVL system the MAC address will be displayed as 8 bytes.
Interface: The port through which this address was learned.
Interface Index: This object indicates the ifIndex of the interface table entry associated with this port.
Status: The status of this entry. The meanings of the values are:
Static:The value of the corresponding instance was added by the system or a user when a static MAC filter was defined. It cannot be relearned.
Learned: The value of the corresponding instance was learned by observing the source MAC addresses of incoming traffic, and is currently in use.
Management:The value of the corresponding instance (system MAC address) is also the value of an existing instance of dot1dStaticAddress. It is identified with interface 1/0/1. and is currently used when enabling VLANs for routing.
Self:The value of the corresponding instance is the address of one of the switch’s physical interfaces (the system’s own MAC address).
GMRP Learned:The value of the corresponding was learned via GMRP and applies to Multicast.
Other:The value of the corresponding instance does not fall into one of the other categories.
If you enter the interface <unit/slot/port> parameter, in addition to the MAC Address and Status fields, the following field appears:
Dynamic Address count: Number of MAC addresses in the forwarding database that were automatically learned.
Static Address (User-defined) count: Number of MAC addresses in the forwarding database that were manually entered by a user.

This command provides the percentage utilization of the CPU by different tasks.
NOTE: It is not necessarily the traffic to the CPU, but different tasks that keep the CPU busy. This command is available in VxWorks and Linux 2.6 only.
Format: show process cpu
Mode: Privileged EXEC
show running-config
Use this command to display or capture the current setting of different protocol packages supported on the switch. This command displays or captures commands with settings and configurations that differ from the default value. To display or capture the commands with settings and configurations that are equal to the default value, include the [all] option.
NOTE: Show running-config does not display the User Password, even if you set one different from the default.
The output is displayed in script format, which can be used to configure another switch with the same configuration. If the optional <scriptname> is provided with a file name extension of “.scr”, the output is redirected to a script file.
NOTE 1: If you issue the show running-config command from a serial connection, access to the switch through remote connections (such as Telnet) is suspended while the output is being generated and displayed.
NOTE 2: If you use a text-based configuration file, the show running-config command will only display configured physical interfaces, i.e. if any interface only contains the default configuration, that interface will be skipped from the show running-config command output. This is true for any configuration mode that contains nothing but default configuration. That is, the command to enter a particular config mode, followed immediately by its exit command, are both omitted from the show running-config command output (and hence from the startup-config file when the system configuration is saved.)
This command captures the current settings of OSPFv2 trapflag status:
If all the flags are enabled, then the command displays trapflags all.
If all the flags in a particular group are enabled, then the command displays trapflags <group name> all
