Address Table Commands:
Dell PowerConnect Switch User's Guide
mac-address-table static
clear mac-address-table dynamic
show mac-address-table
mac-address-table aging-time
show mac-address-table aging-time
mac-address-table static
Use this command to map a static address to a port in a VLAN. Use the no form to remove an address.
Syntax
mac-address-table static mac-address interface vlan vlan-id [action]
no mac-address-table static mac-address vlan vlan-id
l mac-address - MAC address.
l interface
¡ ethernet unit/port
n unit - This is device 1.
n port - Port number.
¡ port-channel channel-id (Range: 1-6)
l vlan-id - VLAN ID (Range: 1-4094)
l action -
¡ delete-on-reset: Assignment lasts until switch is reset.
¡ permanent: Assignment is permanent.
Default Setting
No static addresses are defined. The default mode is permanent.
Command Mode
Global Configuration
Command Usage
l The static address for a host device can be assigned to a specific port within a specific VLAN. Use this command to add static addresses to the MAC Address Table.
Static addresses have the following characteristics:
¡ Static addresses will not be removed from the address table when a given interface link is down.
¡ Static addresses are bound to the assigned interface and will not be moved. When a static address is seen on another interface, the address will be ignored and
will not be written to the address table.
¡ A static address cannot be learned on another port until the address is removed with the no form of this command.
l The maximum number of address entries -
¡ PowerConnect 3248: 8191
¡ PowerConnect 5224: 32768
Example
clear mac-address-table dynamic
Use this command to remove any learned entries from the forwarding database and to clear the transmit and receive counts for any static or system-configured entries.
Default Setting
None
Command Mode
Privileged Exec
Example
Console(config)#mac-address-table static 00-e0-29-94-34-de ethernet 1/1 vlan 1 delete-on-reset
Console(config)#
Console#clear mac-address-table dynamic
show mac-address-table
Use this command to view classes of entries in the bridge-forwarding database.
Syntax
show mac-address-table [address mac-address [mask]] [interface interface] [vlan vlan-id] [sort {address | vlan | interface}]
l mac-address - MAC address.
l mask - Bits to match in the address.
l interface
¡ ethernet unit/port
n unit - This is device 1.
n port - Port number.
¡ port-channel channel-id (Range: 1-6)
l vlan-id - VLAN ID (Range: 1-4094)
l sort - Sort by address, vlan or interface.
Default Setting
None
Command Mode
Privileged Exec
Command Usage
l The MAC Address Table contains the MAC addresses associated with each interface.
l The Type field may include the following types:
¡ Learned - dynamic address entries
¡ Permanent - static entry
¡ Delete-on-reset - static entry to be deleted when system is reset
l The mask should be hexadecimal numbers (representing an equivalent bit mask) in the form xx-xx-xx-xx-xx-xx that is applied to the specified MAC address. Enter
hexadecimal numbers, where an equivalent binary bit “0” means to match a bit and “1” means to ignore a bit. For example, a mask of 00-00-00-00-00-00 means an
exact match, and a mask of FF-FF-FF-FF-FF-FF means "any."
l The maximum number of address entries -
¡ PowerConnect 3248: 8191
¡ PowerConnect 5224: 32768
Example
mac-address-table aging-time
Use this command to set the aging time for entries in the address table. Use the no form to restore the default aging time.
Syntax
mac-address-table aging-time seconds
no mac-address-table aging-time
l seconds - Time is number of seconds
(PowerConnect 5224: 17-2148; PowerConnect 3248: 10-1000000).
Default Setting
300 seconds
Command Mode
Global Configuration
Command Usage
The aging time is used to age out dynamically learned forwarding information.
Console#
Example
show mac-address-table aging-time
Use this command to show the aging time for entries in the address table.
Default Setting
None
Command Mode
Privileged Exec
Example
Please read all restrictions and disclaimers.

Authentication Commands:
Dell PowerConnect Switch User's Guide
authentication login

radius-server port
radius-server key
radius-server retransmit
radius-server timeout
tacacs-server host
tacacs-server port
tacacs-server key
show radius-server
show tacacs-server
You can configure the switch to authenticate users logging into the system for management access using local or authentication-server methods.
Remote Authentication Dial-in User Service (RADIUS) and Terminal Access Controller Access Control System Plus (TACACS+) are logon authentication protocols that use
software running on a central server to control access to RADIUS-aware or TACACS+-aware devices on the network. An authentication server contains a database of multiple
user name/password pairs with associated privilege levels for each user or group that require management access to a switch.
authentication login
Use this command to define the login authentication method and precedence. Use the no form to restore the default.
Syntax
authentication login {[local] [radius] [tacacs]}
no authentication login
l local - Use local authentication.
l radius - Use RADIUS server authentication.
l tacacs - Use TACACS+ server authentication.
Default Setting
Local only
Command Mode
Global Configuration
Command Usage
l RADIUS uses UDP while TACACS+ uses TCP. UDP only offers best effort delivery, while TCP offers a connection-oriented transport. Also, note that RADIUS encrypts
only the password in the access-request packet from the client to the server.
l RADIUS and TACACS+ logon authentication can control management access via the console port, a Web browser, or Telnet. These access options must be
configured on the authentication server.
l RADIUS and TACACS+ logon authentication assigns a specific privilege level for each user name and password pair. The user name, password, and privilege level
must be configured on the authentication server.
l You can specify three authentication methods in a single command to indicate the authentication sequence. For example, if you enter “authentication login radius
tacacs local,” the user name and password on the RADIUS server is verified first. If the RADIUS server is not available, then authentication is attempted on the
TACACS+ server. If the TACACS+ server is not available, the local user name and password is checked.
l If you are using only a RADIUS server for authentication, you need to configure a special user name on the server for the CLI enable command that allows access to
the Privileged Exec level from the Normal Exec level. The user name to configure on the RADIUS server for this command is "$Enable."
Example
Related Commands

radius-server host
Use this command to specify the RADIUS server. Use the no form to restore the default.
