IP Classifier Elements
o
Source IP v4/ v6 host or subnet
o
Destination IP v4/ v6 host or subnet
o
IP v4/ v6 DSCP value
o
IP v4 Protocol type, IP v6 next-header
o
IP v4/ v6 Layer 4 (UDP/ TCP ) Source port
– can be range of ports
o
IP v4/ v6 Layer 4 (UDP/ TCP ) Destination port
– can be range of ports
o
IP v6 flow identifier
A classifier can contain one Layer 2 element, one IP element, or one Layer 2 and one IP element. One or
more classifiers can be combined to creat e a classifier block where up to 15 classifiers and/or classifier
blocks can be assigned to a port. By using classifier blocks, the number of classifiers can be increased up
to a total of 114 classifiers per port on the Ethernet Routing Switch 5500 for a total of over 40K in a stack.
In addition, statistic counters can be used to match/in-profile and out-of-profile statistics with meter. Up to
32 match/in-profile counters and 63 out-of-profile counters (one per meter) are supported per interface.
Actions Supported
After matching a certain classification criteria, various actions can be initiated.
In-profile actions (metered traffic within specific bandwidth limits)
o
Drop
o
Update DS CP
o
Update 802.1p
o
Drop precedence choice of low-drop, high-drop or use egress map
Out-of-profile actions (met ered traffic exceeding bandwidth limits)
o
Drop
o
Update DS CP
o
Set drop prec edence
Non-Match actions (non-metered traffic)
o
Drop
o
Update DS CP
o
Update 802.1p
o
Drop precedence choice of low-drop or high-drop
Metering dat a includes in-profile and out-of-profile actions with metered bandwidth allocated per port.
Each meter has its own token bucket that controls the rate at which packets are accepted for processing
at ingress. The committed information rate (CIR) and bucket sizes are as follows:
o
Committed rate from 1 Mbps to 1 Gbps in 1 Mbps increments, 64K to 1 Gbps in 64K for ERS
5530 only with 10/100/1000 Mbps interfaces
– please see table 6 below for details
o
Token bucket sizes in bytes: 16K, 20K, 32K, 44K, 76K, 140K, 268K, 512K where one byte is sent
for each token
o
Up to 63 counters are available per port
Statistics
The Ethernet Routing Switch 5500 supports tracking of statistics (packet counters) for the policies
defined. The switch can be set-up for one counter for each classifier or a counter for all class ifiers
associated with a policy up to 63 counters are available per port. The statistics track match/in-profile and
out-of-profile statistics associated with a meter.
