Configuring IP Subnet VLANs
show interfaces protocol-vlan protocol-group
This command shows the mapping from protocol groups to VLANs for the selected interfaces.
Syntax
show interfaces protocol-vlan protocol-group [interface]
interface
ethernet unit/port
unit - Unit identifier. (Range: 1)
port - Port number. (Range: 1-12)
port-channel channel-id (Range: 1-12)
Default Setting
The mapping for all interfaces is displayed.
Command Mode
Privileged Exec
Example
This shows that traffic entering Port 1 that matches the specifications for protocol group 1 will be
mapped to VLAN 2:

Configuring IP Subnet VLANs
When using IEEE 802.1Q port-based VLAN classification, all untagged frames received by a port
are classified as belonging to the VLAN whose VID (PVID) is associated with that port.
When IP subnet-based VLAN classification is enabled, the source address of untagged ingress
frames are checked against the IP subnet-to-VLAN mapping table. If an entry is found for that
subnet, these frames are assigned to the VLAN indicated in the entry. If no IP subnet is matched,
the untagged frames are classified as belonging to the receiving port’s VLAN ID (PVID).
