New Hardware and Software Features
Version 5.2.2 provides support for the following new hardware
software features.
Hardware
■80-series, 48-port, 10/100 Ethernet Module with Telco
connectors (M8048R-100TC)
■48-volt power supply for the P580
Software Features
Support for:
■The following Queue Classification and Queue Servicing
features:
—Classification of switch port traffic.
—Classification of layer 2 tagging.
—Classification of layer 3 traffic (by means of an access
control list).
—Queue servicing by means of weighted fair queueing
(WFQ).
For more information about the Queue Classification and
Queue Servicing features that are implemented in this
release, see "Queue Classification and Servicing Features" on
page 4.
■Port mirroring on 80-series modules in fabric mode 2. This
feature makes it possible for you to:
—Monitor traffic that is received and transmitted from a
port.
—Use of up to four monitor (sink) channels for monitoring
traffic.
For more information about the port mirroring on 80-series
module feature that is implemented in v5.2.2, see "Queue
Classification and Servicing Features" on page 4.

■Relay Agent Information option (option 82) for Dynamic
Host Configuration Protocol (DHCP). When forwarding
client-originated DHCP packets to a DHCP server, the Cajun
switch inserts this option, which contains information about
the switch. The DHCP server uses this information to
authenticate the client.
For information on how to enable option 82, see "Enabling
Option 82 for DHCP" on page 12 of this document.
■Enhancement of the MAC Address Lock feature. This feature
has been available in all previous releases. If a source MAC
address is locked at a port (statically configured), a frame
with that source MAC will be filtered if received on any other
port on the same VLAN. With the enhancement, the feature
immediately generates traps to identify all unknown source
addresses. If, after sending a trap for an unknown source, the
switch continues to receive traffic from the source, the
feature generates a trap every 30 minutes until the traffic
stops.
* Note: You can set the trap timer within a range of 60 to
1800 seconds (default) in one second intervals.
For information on how to enable the MAC Address Lock
feature and traps for unknown source addresses, see
"Enabling Traps for Unknown Source Addresses" on page 14
of this document.
■Load MIB for the ATM Uplink module, v1.1. This feature
makes it possible for you to use SNMP commands to:
—Upload the startup configuration file of the ATM Uplink
module to a TFTP server
—Download the startup configuration file from a TFTP
server to the ATM Uplink module.
—Download a software image to the ATM Uplink module.

supported by v5.2.2 of the Cajun switch software.
* Note: Before downloading and running v5.2.2, remove port
mirrors with piggyback ports on 80-series modules.
Table 1. v5.2.2 Product Binary and Boot Files
* Note: The m8000r binary files run the supervisor module
on both the P580 and P882 switches. These files
replace the m8820_vx.x.x files.
Queue Classification and Servicing Features
Overview
Version v5.2.2 contains Queue Classification and Servicing
functionality that you can activate from the switch’s CLI. You can
configure Queue Classification and Servicing functionality for a
module, or for individual ports on a module. The main components
of the Queue Classification and Servicing functionality are:
■A hierarchical classification mechanism that classifies
incoming traffic
■Priority queues through which the switch forwards classified
traffic.
The switch first classifies the traffic and then, based upon the
classification of the traffic, stores it in the appropriate priority queue.
The switch services the queues according to the WFQ algorithm and
assigns queue weights.

Classification of Traffic
You can classify traffic by:
■802.1p tag priority (default)
■Physical source port
■IP characteristics of the frame (source address, destination
address, and so forth)
Frames are classified into eight priorities, or classes, ranging in
number from 0 to 7. By default, the switch uses the priority from
the 802.1p tag field, if present, to assign a priority to a frame.
You can alternately set each physical port with a priority that ranges
from 0 to 7. The switch then replaces the default 802.1p tag priority
with the port priority as the priority of the frame.
You can, as a third alternative, set classification to be performed by
the IP characteristics of packets, instead of 802.1 tag priority or port
priority. To classify frames by their IP characteristics, you set a rule
in an access control list (ACL). The rule can set a priority for traffic
with a specific IP source address or with a specific combination of IP
source address, IP destination address, IP protocol, TCP source port,
and TCP destination port.
The priority of a rule in an ACL takes precedence over all other
priorities in Queue Classification and Servicing classification.
Because of this precedence, the switch determines whether a rule in
an ACL exists for an IP frame in the final stage of classification. If a
rule does exist, the priority associated with the rule replaces the
current priority of the frame.
The switch then forwards the frames to the appropriate priority
queue based upon the priority that is assigned to the frames.

WFQ Queue-Servicing Algorithm
You can configure the WFQ service policy. The WFQ policy
implemented in the Cajun II Queue Classification and Servicing
sub-system is a variation of the textbook WFQ algorithm. In Cajun II
WFQ, each queue is assigned a weight increment. The weight
increment never varies; however, each queue also maintains an
accumulated weight, which is updated after each queue service
cycle. Queues are serviced based upon their relative accumulated
weights. In each queue service cycle, only the queue with the
highest accumulated weight is serviced. If there is a tie, the queue
with the highest priority (0 – 7 highest) is serviced first. After each
queue service cycle, the accumulated weight for the queue that is
serviced is reset to the value of its weight increment, and the
accumulated weight for the other queues is increased by their
respective weight increments.
When you set a port for WFQ, the switch services priority queues
according to their assigned weight. The queue with the highest
weight is serviced first.
There are two levels to the WFQ command. The first level specifies
the modules/ports to be configured. The second level specifies the
queue weights.
Port Mirroring on 80-Series Modules
The port mirroring on 80-series modules that is implemented in
v5.2.2 provides the ability for the 80-series modules to monitor
traffic that a port transmits and receives. Four channels are provided
for monitoring traffic, so you can monitor four different ports or
port ranges simultaneously.
* Note: Your switch must be in fabric mode 2 to perform 80-series
port mirroring.
You can configure port mirroring on 80-series modules by using
either the command-line interface (CLI) or the Web Agent.

Configuring Port Mirroring By Using the CLI
Use the following CLI commands to configure port mirroring on 80-
series modules. You must be in Global Configuration command
mode to enter these commands.
* Note: For information on how to enter Global Configuration
command mode, see “Accessing/Exiting the Command
Modes” in chapter 1 of Cajun P550R/P880/P882 Command
Reference Guide.
Setting Up Port
Mirroring
To set up port mirroring, use the following CLI command:
>(config)# set port mirror fabric_mode2
source-port <mod-port-range> mirror-port
<mod-port-spec> channel <channel> direction
{tx | rx | both} sampling {always | disable |
periodic} [max-packets=sec <max-packets-sec-
value>]
where:
■<mod-port-range> is either the single port or the range of
ports that you want to mirror.
See Table 2 on page 8 for the specific port ranges that you can
mirror.

Table 2. Port Ranges for 80-Series Port Mirroring
Module Port ranges that you can mirror
4-port gigabit modules • 1–2
• 3–4
• Any single port
You can mirror any four single
ports simultaneously (one port per
channel). However you cannot
mirror a port range and a single
port within that range
simultaneously.
Example: You can mirror port 1
on channel 1, port 2 on channel 2,
and port 3 on channel 3
simultaneously. However, you
cannot mirror ports 1 through 2 on
channel 1 and port 2 on channel 2
simultaneously.
8-port gigabit modules • 1–4
• 5–8
• Any single port
You can mirror any four single
ports simultaneously (one port per
channel). However you cannot
mirror a port range and a single
port within that range
simultaneously.
Example: You can mirror port 1
on channel 1, port 2 on channel 2,
and port 3 on channel 3
simultaneously. However, you
cannot mirror ports 1 through 4 on
channel 1 and port 2 on channel 2
simultaneously.

* Note: You cannot mirror transmit traffic of multiple
source ports to one mirror port.
■<mod-port-spec> is the port to which you want to mirror
traffic.
Both the source port and mirror port must either:
—Be on the same vlan and have the same vlan binding
or
—Have vlan binding set to bind to all
24-port 10/100 modules • 1–12 — any 1 port or the
entire range.
• 13–24 — any 1 port or the
entire range.
If you mirror a single port, you can
mirror only 1 port per range at a
time.
Example: You can mirror port 1
on channel 1 and port 13 on
channel 2 simultaneously.
However, you cannot mirror port 1
on channel 1 and port 2 on
channel 2 simultaneously.
48-port 10/100 modules • 1–12 — any 1 port or the
entire range.
• 13–24 — any 1 port or the
entire range.
• 25–36 — any 1 port or the
entire range.
• 36–48 — any 1 port or the
entire range.
If you mirror a single port, you can
mirror only 1 port per range at a
time.
Example: You can mirror port 1
on channel 1 and port 13 on
channel 2 simultaneously.
However, you cannot mirror port 1
on channel 1 and port 2 on
channel 2 simultaneously.

* Note: Avaya recommends that you mirror traffic to a port
of the same speed or faster than the source port.
■<channel> is the mirror channel that you want to use (1-4).
■{TX| RX |Both} is the direction of traffic that you want to
mirror.
* Note: You can mirror transmit traffic of only one source
port to the mirror port. You cannot mirror transmit
traffic of multiple source ports to one mirror port.
■{always | disable | periodic} is how often you
want the mirror port to receive traffic samples.
■<max-packets-sec-value> is the maximum number of
packets per second that you want the mirror port to receive.
(Enter a value for this variable only if you set the sampling to
periodic.)
Removing Port
