IP Addressing

through DHCP that corresponds to a real address from one of the SMS2000’s DHCP pools.

Note: Addresses in the DHCP pool must be in the same subnet as the SMS2000 or in a control-net.

For example,

sms2000% group add dhcpers

sms2000% dhcp-pool mypool 192.168.0.100 192.168.0.110 255.255.255.0 lease 80 sms2000% iptype dhcp

sms2000% set rule bob 1 mac=00:01:02:03:04:05

Static Non-Routable Addresses

A fixed address can be assigned to a subscriber. Static non-routable addresses with SMS2000 rules are configured in RADIUS or OCS. Subscribers who want to use their assigned static non-routable addresses must set their client TCP/IP configurations with the assigned addresses. If they use any other address or DHCP, they will still receive service but their traffic will go through NAT.

IP Multicasting

Ethernet multicast packets are translated by the SMS2000 before being sent to the subscriber ports. The SMS2000 snoops IGMP between a multicast querier, such as a multicast router or a content server, and hosts. The SMS2000 translates Ethernet multicast MAC addresses to unicast MAC addresses; multicast packets received on the network side of the SMS2000 are translated to unicast traffic on the subscriber side. Only clients participating in IGMP receive multicast content.

A querier, such as a full feature multicast router or a content server, sends IGMP queries on its local network. The SMS2000 forwards these queries (which are Ethernet broadcasts) to each of the subscribers. If the subscribers are on VLAN switches, the SMS2000 sends the query as a broadcast to each of the active VLANs. By snooping the response from subscribers, the SMS2000 tracks whether each individual client is requesting a multicast stream. If a subscriber fails to respond to three consecutive queries for a particular multicast group or if the subscriber sends an IGMP“leave,” the SMS2000 stops sending the multicast content.
