Port Mobility Commands

vlan protocol
Defines a protocol rule for an existing VLAN. If a device sends traffic that matches the protocol value
specified in the rule, the device and its mobile port will join the rule’s VLAN.
vlan vid protocol {ip-e2 | ip-snap | decnet | appletalk |
ethertype type | dsapssap dsap/ssap | snap snaptype}
vlan vid no protocol {ip-e2 | ip-snap | decnet | appletalk |
ethertype type | dsapssap dsap/ssap | snap snaptype}
Syntax Definitions
vid VLAN ID number (1–4094).
ip-e2 IP Ethernet-II protocol. Also captures Address Resolution Protocol
(ARP).
ip-snap IP Sub-network Access Protocol (SNAP) protocol.
decnet DECNET Phase IV (6003) protocol.
appletalk AppleTalk protocol. Also captures Datagram Delivery Protocol (DDP)
and AppleTalk ARP (AARP).
type A two-byte hex value between 0x600 and 0xffff that defines an Ether-
net type (e.g., 0600, 0806, 6002).
dsap/ssap A one-byte hex value between 0x00 and 0xff that defines Destination
Service Access Protocol (DSAP) and Source Service Access Protocol
(SSAP) header values. Specify both a DSAP and an SSAP value for this
parameter variable (e.g., F0/F0, 04/04, BC/BC).
snaptype A two-byte hex value between 0x600 and 0xffff that defines a SNAP
protocol.

Usage Guidelines
• Use the no form of this command to delete a protocol rule from the specified VLAN.
• Use the ethertype, dsapssap, or snap parameters if none of the generic protocol rule parameters (ip-
e2, ip-snap, decnet, appletalk) provide the necessary rule definition for a specific traffic protocol.
• If an attempt is made to define an Ethertype rule with a protocol type value that is equal to the value
already captured by one of the generic IP protocol rules, a message displays recommending the use of
the IP generic rule.
• Protocol rules take precedence behind DHCP, binding, MAC address, and network address rules.
