AT-8800 Series Switch User Guide

Internet Protocol (IP)

The switch performs IP routing at wire speed between VLANs that have been configured as IP interfaces. For example, to add the admin VLAN as an IP interface, giving it an IP address of 192.168.163.39 in the subnet 192.168.163.0, first enable IP using the command:

ENABLE IP

Then use either of the following commands:

ADD IP INTERFACE=vlan-admin IPADDRESS=192.168.163.39

MASK=255.255.255.0

ADD IP INTERFACE=vlan11 IPADDRESS=192.168.163.39

MASK=255.255.255.0

The command:

SHOW IP INTERFACE

displays the interfaces enabled for IP routing (Figure 22).

IP Multicasting

Static multicast forwarding can be configured using the ADD IP INTERFACE or SET IP INTERFACE commands.

The switch supports dynamic IP multicast routing protocols:

■DVMRP (Distance Vector Multicast Routing Protocol)

■PIM-DM (Protocol Independent Multicast – Dense Mode)

■PIM-SM (Protocol Independent Multicast – Sparse Mode).

Management of group members is performed using IGMP (Internet Group Management Protocol). IGMP snooping reduces unnecessary multicast traffic between members of the same VLAN.

Full multicast functionality requires IGMP and at least one of DVMRP, PIM

Dense Mode or PIM Sparse Mode. See the IP Multicasting chapter in the Rapier

Switch Software Reference for detailed information about multicasting.
