captive-portal

bridge

Enables IP (IPv4 and IPv6) packet snooping on wired captive portals, and also configures the subnet to snoop. When enabled, IP packets received from wired captive portal clients, on the specified subnet, are snooped to learn IP to MAC mapping.

Supported on the following devices:

Access Points: AP3000/X, AP5010, AP310i/e, AP410i/e, AP505i, AP510i, AP510e, AP560i, AP7602, AP7612, AP7622, AP7632, AP7662, AP8163, AP8533.
Service Platforms: NX5500, NX7500, NX9500, NX9600
Virtual Platforms: CX9000, VX9000

Syntax

captive-portal [ipv4-snooping|ipv6-snooping] subnet <IPv4/M|IPv6/M> {excluded-address <IPv4|IPv6>}

Parameters

captive-portal [ipv4-snooping|ipv6-snooping] subnet <IPv4/M|IPv6/M> {excluded-address <IPv4|IPv6>}


captive-portal [ipv4-snooping\| ipv6-snooping]	Enables snooping of IPv4 or IPv6 packets (based on the option selected) for wired captive portal clients
subnet <IPv4/M\| IPv6/M>	Enables IPv4 or IPv6 packet snooping on a specified subnet <IPv4/M\|IPv6/M> – Specify the subnet address in the A.B.C.D/M or X:X::X:X/M format to identify an IPv4 or IPv6 subnet respectively. When specified, this is the IPv4/IPv6 subnet on which IP packets are to be snooped.
excluded-address <IPv4\|IPv6>	Optional. Configures the IPv4 or IPv6 address excluded from snooping within the specified IPv4\|IPv6 subnet. <IPv4\|IPv6> – Specify the IPv4 or IPv6 address. Use this parameter to configure the gateway‘s address.
