TCP/UDP port ranges can only have sizes of 2
n
, where the lower port of the
range is aligned to the range number.
— For example, for a range of 32 ports (2
5
), the lower ports can have the value
of 32, 64, 96, etc.
— This limitation does not apply when the device is in “Router” policy type.
•
Only L3 rules (based on Src/Dest IP address) will be enforced on IP fragments.
Therefore, if an L4 rule is applicable to an IP fragment, the fragment will be
dropped.
Therefore, if an L4 rule is applicable to an IP fragment, the fragment will be
dropped.
•
The following rules are not supported for TCP/UDP port numbers:
— “lower then”
— “greater then”
— “lower then”
— “greater then”
•
If a packet matches a rule with a “permit” action and subsequently a rule with
“fwd…” action, the packet’s priority will be changed to the one specified in the
second rule, instead of being forwarded with the original priority as per
“permit” action
— This limitation is relevant only for Layer 2 policy (i.e., when the policy type
“fwd…” action, the packet’s priority will be changed to the one specified in the
second rule, instead of being forwarded with the original priority as per
“permit” action
— This limitation is relevant only for Layer 2 policy (i.e., when the policy type
is “all”).
Configuring the P334T-ML for Multilayer Policy
This section describes the configuration of the P334T-ML for Multilayer Policy
functionality.
functionality.
Configuration Requirements
The following specific requirements impact on the configuration of Multilayer
Policy in an Avaya P334T-ML:
•
Policy in an Avaya P334T-ML:
•
Multilayer Policy must be configured separately on each P334T-ML in the stack.
This is done by opening a “session” to the module.
This is done by opening a “session” to the module.
•
If the device Mode is “Layer 2,” the policy commands will appear in the L2 CLI
tree; if the Device Mode is “Router,” the commands will appear in the L3 CLI
tree.

•
Policy List validation will be performed during list activation.
•
A CLI command for policy simulation is available.
Configuration File Management
The following specific requirements impact on the management of the Multilayer
Policy configuration file:
•
Policy configuration file:
•
Unlike other Layer 2 settings, the Layer 2 policy is not automatically saved in
NVRAM. In order to save the Layer 2 or Layer 3 policy configuration, the user
must copy the running configuration to the startup configuration file. To do
this, use the command copy running-config startup-config.
