Defining Protocol Rules - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Defining VLAN Rules
In this example, frames received on any mobile port must contain an IPX network a010590c address with
a Novell Raw (802.3) encapsulation to qualify for dynamic assignment to VLAN 1200.
IPX network addresses consist of eight hex digits. If an address less than eight digits is entered, the entry
is prefixed with zeros to equal eight characters. For example, the following command results in an IPX
network address rule for network 0000250b:
-> vlan 1210 ipx 250b snap
If an encapsulation parameter value is not specified, this value defaults to Ethernet-II encapsulation. For
example, either one of the following commands creates the same IPX network address rule:
-> vlan 1220 ipx 250c e2
-> vlan 1220 ipx 250c
If the IPX network address rule VLAN is going to route IPX traffic, it is important to specify a rule encap-
sulation that matches the IPX router port encapsulation. If there is a mismatch, connectivity with other
IPX devices may not occur. See
IPX router ports.
The following table lists keywords for specifying an encapsulation value:

Use the no form of the
necessary to specify the IPX network address to identify which rule to remove.
-> vlan 1220 no ipx 250c

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):
