based on access lists, IP Precedence or DSCP values, or VLAN lists. Using access lists
allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained
in each packet. Based on network policies, different kinds of traffic can be marked
for different kinds of forwarding.
IP Routing The switch provides Layer 3 IP routing. To maintain a high rate of throughput, the
switch forwards all traffic passing within the same segment, and routes only traffic
that passes between different subnetworks. The wire-speed routing provided by
this switch lets you easily link network segments or VLANs together without having
to deal with the bottlenecks or configuration hassles normally associated with
conventional routers.
Routing for unicast traffic is supported with static routing and Routing Information
Protocol (RIP).
Static Routing – Traffic is automatically routed between any IP interfaces
configured on the switch. Routing to statically configured hosts or subnet
addresses is provided based on next-hop entries specified in the static routing
table.
RIP – This protocol uses a distance-vector approach to routing. Routes are
determined on the basis of minimizing the distance vector, or hop count, which
serves as a rough estimate of transmission cost.
Address Resolution
Protocol
The switch uses ARP and Proxy ARP to convert between IP addresses and MAC
(hardware) addresses. This switch supports conventional ARP, which locates the
MAC address corresponding to a given IP address. This allows the switch to use IP
addresses for routing decisions and the corresponding MAC addresses to forward
packets from one hop to the next. Either static or dynamic entries can be
configured in the ARP cache.
Proxy ARP allows hosts that do not support routing to determine the MAC address
of a device on another network or subnet. When a host sends an ARP request for a
remote network, the switch checks to see if it has the best route. If it does, it sends
its own MAC address to the host. The host then sends traffic for the remote
destination via the switch, which uses its own routing table to reach the destination
on the other network.
Multicast Filtering Specific multicast traffic can be assigned to its own VLAN to ensure that it does not
interfere with normal network traffic and to guarantee real-time delivery by setting
the required priority level for the designated VLAN. The switch uses IGMP Snooping
and Query for IPv4,and MLD Snooping and Query for IPv6 to manage multicast
group registration.
