Creating and Assigning IP Interfaces to the VLAN

Web Agent Procedure

After you have set up a VLAN, you must create the IP interface that your VLAN and your subnet uses to communicate with each other. While creating the IP interface, you must assign it to the VLAN. The last step is to enable IP forwarding (Routing) global parameters.

To create a new IP interface and assign it to a VLAN:

  1. In the navigation pane, expand the Routing > IP > Configuration folders, and then click Interfaces. The IP Interfaces Web page is displayed in the content pane. See Figure�93.
  2. Click CREATE. The Add IP Interface Web page is displayed. See Figure�94.

Figure�94:�Add IP Interface Web page


Table�62:�Add IP Interface Parameters �
Parameter
Description
Name
Enter a unique, alphanumeric name for the interface (maximum 30 characters)
VLAN
A pull down menu that associates a VLAN with this IP Interface.

Note: The way that you configure a port(s) to a VLAN determines the IP Routing option that you select for the interface. Use the following options to configure the appropriate interface:

  • Default - Selects the default VLAN.(VLAN ID=1)
  • Discard - Selects the VLAN to be discarded.(VLAN ID= 4097)
  • VLANs- A list of all VLANs created on the switch.

Note: The following two parameters, Ethernet-Console and Serial-Console are special IP interface settings, and are not part of the normal routed data path. Do not configure routing only or routing and management for the serial interface or the Ethernet Console, configure both for management only.

  • Ethernet-Console - Creates an IP interface and assigns the IP address to the Supervisor's Ethernet port.
  • Serial Console - Creates an IP interface and assigns the IP address to the Supervisor's serial port (RS232). This is necessary if you are using PPP to connect to the supervisor's serial port.
Interface Type
Ethernet LAN or NBMA.
Non-Broadcast Multi-Access (NBMA) IP Interfaces. Makes it possible for the switch to exchange routing information over nonbridged connections (routed virtual switch ports (VSPs))
NBMA functionality was added to RIP and OSPF routing protocols on the Avaya Multiservice switch software.
Administrative State
Specify the administrative state of the interface. Options include:
  • UP - The interface is active.
  • DOWN - The interface is inactive.
Network Address
Enter the network IP address for the selected interface.
Mask
Enter the subnet mask for the interface.
MAC Format
Select the MAC address format for the interface.
Options include:
  • Ethernet V2
  • Simple Network Access Protocol (SNAP)
ARP Timeout
Enter the timeout period for Address Resolution Protocol (ARP) in seconds.The ARP Timeout value is the period of time the switch will wait for data from a station, if no data is received, the station is deleted from the ARP Table.
The default is 14,400 seconds (4 hours).
Directed Broadcast
When the IP Directed Broadcast feature is Enabled, it allows a Network Directed Broadcast (unicast IP address with the Host ID set to all One's) to be forwarded by the router on the selected interface. The default is Enable.
IP Routing
Select enable or disable IP routing on the interface. Options include:
  • Routing/Mgmt (Default) - Enables you to manage the switch, from the Command Line Interface (CLI) or the Web Agent, and configure IP routing for the switch.
  • Mgmt Only - Enables you to manage the switch, however, IP routing is disabled for this interface.
    A management only interface is intended for use by end stations. Only a client directly connected to the interface can manage the switch from that interface. You cannot log in to a management only interface from a client that is connected to a routing/management interface.

Note: Do not enable routing protocols on an interface configured for Mgmt Only since the interface will act as an end point and will not pass traffic.

  • Routing Only - IP routing is enabled on the interface, but you cannot manage the switch through the interface. Routing Only interfaces do not permit management traffic destined for local interfaces but do allow all other traffic including management traffic destined for interfaces on other switches.
RIP
Enable or disable RIP. The default value is Disable.
OSPF
Enable or disable OSPF. The default value is Disable.

Note: To Enable OSPF, The Admin State of the IP interface must be set to down. Enable OSPF and then set the Admin State to up.

Multicast Protocol
Specify the multicast protocol for the interface. Options include:
  • None (Default)
  • DVMRP
  • IGMP

Note: By Default, multicast forwarding is disabled. To enable multicast forwarding go to the IP Global Configuration page.

Proxy ARP
Enable or disable Proxy ARP. The default value is Disable.
ICMP Redirect
Enable or disable ICMP Redirect (IDRP). The default value is Enable.
NetBIOS UDP Rebroadcast
Enable or disable NetBIOS UDP Rebroadcasts. The default value is Disable.
VRRP
Enable or disable Virtual Redundancy Router Protocol. The default value is Disable.
BOOTP/DHCP Relay Gateway
Enable or disable the BOOTP/DHCP Relay Agent. The default value is Enable.
