Parameters
ip [arp|dhcp] trust
ip igmp snooping {forward-unknown-multicast}
ip igmp snooping {mrouter [interface |learn pim-dvmrp]}
ip Configures the VLAN bridge IP parameters
arp trust Configures the ARP trust parameter. Trusted ARP packets are used to update the DHCP snoop table to
prevent IP spoof and arp-cache poisoning attacks. This option is disabled by default.
•
trust – Trusts ARP responses on the VLAN bridge
dhcp trust Configures the DHCP trust parameter. Uses DHCP packets, from a DHCP server, as trusted and
permissible within the access point, wireless controller, or service platform managed network. DHCP
packets are used to update the DHCP snoop table to prevent IP spoof attacks. This feature is disabled by
default.
•
trust – Trusts DHCP responses on the VLAN bridge
ip Configures the VLAN bridge IP parameters
igmp snooping Configures Internet Group Management Protocol (IGMP) snooping parameter
The IGMP protocol establishes and maintains multicast group memberships for interested members.
Multicasting allows a networked device to listen to IGMP network traffic and forward IGMP multicast
packets to radios on which the interested hosts are connected. The device also maintains a map of the
links that require multicast streams, there by reducing unnecessary flooding of the network with multicast
traffic.
forward-unknown-multicast Optional. Enables forwarding of multicast packets from unregistered multicast groups. If disabled, the
unknown multicast forward feature is also disabled for individual VLANs. This option is disabled by
default.
ip Configures the VLAN bridge IP parameters
igmp snooping Configures the IGMP snooping parameters
mrouter Optional. Configures the multicast router parameters
interface
Configures the multicast router interfaces
•
– Specify a comma-separated list of interface names.
learn pim-dvmrp Configures the multicast router learning protocols
•
pim-dvmrp – Enables Protocol-Independent Multicast (PIM) and
Distance-Vector Multicast Routing Protocol (DVMRP) snooping of packets
