Port Mobility Commands

OmniSwitch CLI Reference Guide

Defines an IP network address rule for an existing VLAN. If a device sends traffic that matches the IP 
address specified in the rule, the device and its mobile port will join the rule’s VLAN.

Note. On an OmniSwitch 6800, IP network address rules are applied to traffic received on both mobile 
and fixed (non-mobile) ports. As a result, fixed port traffic that contains an IP address that is included in 
the IP subnet specified by the rule is dropped. However, if the IP network address rule VLAN is also the 
default VLAN for the fixed port, then the fixed port traffic is forwarded and not dropped.

vlan vid ip ip_address [subnet_mask]

vlan vid no ip ip_address [subnet_mask]

VLAN ID number (1–4094).

IP network address (e.g., 10.0.0.0, 171.15.0.0, 196.190.254.0)

Class A, B, or C subnet mask (e.g., 255.0.0.0, 255.255.0.0, or 
255.255.255.0).

By default, the subnet mask is set to the default subnet mask value for the IP address class.

• Use the no form of this command to delete an IP network address rule from the specified VLAN.

• Network address rules take precedence behind DHCP, binding, and MAC address rules.

• Note that on an OmniSwitch 6800 when the contents of a mobile port frame matches the values speci-

fied in both an IP network address rule and a port-protocol binding rule, the IP network address rule 
takes precedence. However, if the contents of such frame violates the port-protocol binding rule, the 
frame is dropped.

• Use DHCP rules in combination with IP network address rules to capture and forward DHCP traffic.

• Rules are only assigned to existing VLANs. Use the vlan command to create a new VLAN.
