Configuration Commands

This section includes Interface configuration commands.

alias - For interface

Command Objective:

This command configures the alias name for the interface/L3 Subinterface. This value is a string of maximum size 63.

Syntax:
alias <string(63)>

Mode:
Interface Configuration Mode / Sub Interface Configuration Mode

Example:

Your Product (config-if)# alias interface1

Your Product (config-subif)# alias interface1

bridge port-type

Command Objective:
This command configures the bridge port type for an interface.

Syntax:
bridge port-type { providerNetworkPort | providerNetworkPort three-tagged | customerNetworkPort port-based | customerEdgePort }

Parameter Description:

• providerNetworkPort - Sets the bridge port type as provider network port. This option is the default value. The port is connected to a single provider.
• providerNetworkPort three-tagged - Sets the bridge port-type as a provider network port with a third VLAN. The third VLAN is a Tunnel VLAN component.
• customerNetworkPort port-based - Customer network port; sets the bridge port type as port based.
• customerEdgePort - Sets the bridge port type as Customer Edge Port. The port is in a PEB that is connected to a single customer.

  The packets received on this port are initially classified to a C-VLAN. C-VLAN classification is done based on the VID in the C-tag present in the packet or from the PVID of the port. Service instance selection is done for a frame based on the entry present in the C-VID registration table for the pair (C-VID, reception port).

Mode:
Interface Configuration Mode

The port type cannot be set for a port that is part of a port-channel.

Example:

Your Product(config-if)# bridge port-type providerNetworkPort    

default IP Address

Command Objective:

This command configures the IP address and subnet mask for the default interface.

Syntax:

default ip address < ip-address > [ subnet-mask < subnet mask > ] [ interface < interface-id > ]

Parameter Description:

• < ip address > - Sets the IP address for the default interface / specified interface. If the network in which the switch is implemented contains a server such as DHCP server, dynamically allocating IP address, the configured IP address should not be within the range of the addresses that will be allocated by the server to the other switches. This precaution avoids creation of IP address conflicts between the switches.
• subnet-mask < subnet mask > - Sets the subnet mask for the configured IP address. The configured subnet mask should be in the same subnet of the network in which the switch is placed
  

  ---

  Note: If the subnet-mask is not specified, then it will be derived automatically from the class of the configured "ip address".

  ---

• < interface-type > - Sets the IP address and / or subnet mask for the specified type of interface. The interface can be:
• fastethernet – Officially referred to as 100BASE-T standard. This is a version of LAN standard architecture that supports data transfer up to 100 Megabits per second.
• gigabitethernet – A version of LAN standard architecture that supports data transfer up to 1 Gigabit per second.
• extreme-ethernet – A version of Ethernet that supports data transfer upto 10 Gigabits per second. This Ethernet supports only full duplex links.
• i-lan – Internal LAN created on a bridge per IEEE 802.1ap.
• < interface-id > - Sets the IP address and / or subnet mask for the specified interface identifier. This is a unique value that represents the specific interface. This value is a combination of slot number and port number separated by a slash, for interface type other than i-lan. For Example: 0/1 represents that the slot number is 0 and port number is 1. Only i-lan ID is provided, for interface type i-lan. For Example: 1 represents i-lan ID.

Mode:

Global Configuration Mode

Default:

• ip address - 10.0.0.1
• subnet-mask - 255.0.0.0

Example:

Your Product(config)# default ip address 20.0.0.1 subnet-mask 255.0.0.0 interface gigabitethernet 0/1

ip address

Command Objective:

This command sets the IP address for an interface.

The no form of the command resets the IP address of the interface to its default value.

Syntax:

ip address < ip-address > < subnet-mask > [secondary]

ip address < ip-address > < subnet-mask >

ip address < ip-address > < subnet-mask > [secondary] [gateway < ip-address >]

ip address < ip-address > < subnet-mask > [secondary {node0 | node1}]

no ip address [< ip_addr >]

no ip address < ip-address > < subnet-mask >

no ip address [secondary {node0 | node1}]

Parameter Description:

• < ip-address >/<ip_addr> - Sets the IP address for an interface. If the network in which the switch is implemented contains a server such as DHCP server, dynamically allocating IP address, the configured IP address should not be within the range of the addresses that will be allocated by the server to the other switches. This precaution avoids creation of IP address conflicts between the switches.

• < subnet-mask > - Sets the subnet mask for the configured IP address. The configured subnet mask should be in the same subnet of the network in which the switch is placed.
  

  ---

  Note: The parameters ip-address and subnet-mask are used implicitly in BCM Target.

  ---

• secondary - Sets the configured IP address as an additional IP address for the interface (the configured address is used as secondary address instead of primary address).
  

  ---

  Note: This parameter is not supported on the OOB and PPP interface.

  ---

• gateway ip-addres> - Sets the gateway Next hop for default gateway route.

• node0 - Specifies the secondary IP address associated with the OOB interface of Node0

• node1 - Specifies the secondary IP address associated with the OOB interface of Node1

Mode:

Interface Configuration Mode

Default:

• IP address specified in issnvram.txt is taken as default for the default VLAN identifier.
• IP address is assigned as 0.0.0.0 and subnet mask as 255.255.255.255 for other interfaces.

Prerequisites:

• The interface should be shutdown before executing this command.
• The Primary and secondary IP address should be different.
• Primary address should be configured before configuring the secondary address.
• The connection to the switch is lost if the IP address of the connected interface is modified
• When the same network interface is used for OOB and NFS mounting, the operation done on OOB will have an impact on NFS.
• For PPP mode, the PPP interface should be attached to the physical interface first.

Example:

Your Product(config-if)# ip address 10.0.0.3 255.255.255.0

Your Product(config-if)# ip address 10.0.0.2 255.255.255.0 secondary

Your Product(config-subif)# ip address 10.0.0.3 255.255.255.0

Your Product(config-subif)# ip address 10.0.0.2 255.255.255.0 secondary

Your Product (config-ppp)# ip address 17.0.0.100 255.255.255.0

ip address - rarp/dhcp

Command Objective:

This command configures the current VLAN / OOB interface to dynamically acquire an IP address from the RARP / DHCP server.

The no form of the command resets the IP address for the interface to its default value.

Syntax:

ip address { dhcp | rarp}[client-id { FastEthernet | GigabitEthernet | Port-channel | Vlan } <interface_list>] [hostname <host_name>]

no ip address

Parameter Description:

• dhcp - Allows the client device to obtain configuration parameters such as network address, from the DHCP server.
• rarp - Allows the client device to dynamically find its IP address from RARP server, when it has only its hardware address such as MAC address.
• client-id - Sets the client identifier that specifies the interface type and hexadecimal MAC address of the specified interface. The various interface types that can be specified are:
• FastEthernet - Officially referred to as 100BASE-T standard. This is a version of LAN standard architecture that supports data transfer up to 100 Megabits per second.
• GigabitEthernet - A version of LAN standard architecture that supports data transfer up to 1 Gigabit per second.
• Port-channel - Logical interface that represents an aggregator which contains several ports aggregated together.
• Vlan - Logical interface that specifies a group of hosts which can communicate with each other as in the same broadcast domain.
• < interface list > - Sets the list of interfaces or a specific interface identifier. This value is a combination of slot number and port number separated by a slash, for interface types other than port-channel and VLAN. Only VLAN or port-channel ID is provided, for interface types VLAN and port-channel. Use comma as a separator without space while configuring a list of interfaces. Example: 0/1,0/3 or 1,3. Feature not supported - This feature has been included to adhere to the Industry Standard CLI syntax. This feature is currently not supported.
• hostname - Sets the name of the host from which the IP address is to be acquired dynamically. Feature not supported - This feature has been included to adhere to the Industry Standard CLI syntax. This feature is currently not supported.

Mode:
