Configuring VLAN Rule Definitions
Defining Protocol Rules
Protocol rules capture frames that contain a protocol type that matches the protocol value specified in the
rule. There are several generic protocol parameter values to select from; IP Ethernet-II, IP SNAP, IPX
Ethernet II, IPX Novell (802.3), IPX LLC (802.2), IPX SNAP, DECNet, and Appletalk. If none of these
are sufficient to capture the desired type of traffic, use the Ethertype, DSAP/SSAP, or SNAP parameters to
define a more specific protocol type value.
To define a protocol rule, enter vlan followed by an existing VLAN ID then protocol followed by a valid
protocol parameter value. For example, the following commands define a protocol rule for VLAN 1503
and VLAN 1504:
-> vlan 1503 protocol ip-snap
-> vlan 1504 protocol dsapssap f0/f0
The first example command specifies that frames received on any mobile port must contain an IP SNAP
protocol type to qualify for dynamic assignment to VLAN 1503. The second command specifies that
frames received on any mobile port must contain a DSAP/SSAP protocol value of f0/f0 to qualify for
dynamic assignment to VLAN 1504.
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 or IPX protocol rules, a message displays recommending the use
of the IP or IPX generic rule. The following example shows what happens when an attempt is made to
create a protocol rule with an Ethertype value of 0800 (IP Ethertype):
-> vlan 200 protocol ethertype 0800
ERROR: Part of ip ethernet protocol class - use <vlan # protocol ip-e2> instead
The following table lists keywords for specifying a protocol type:
protocol type keywords
ip-e2
ip-snap
ipx-e2
ipx-novell
ipx-llc
ipx-snap
Note that specifying a SNAP protocol type restricts classification of mobile port traffic to the ethertype
value found in the IEEE 802.2 SNAP LLC frame header.
Use the no form of the
