How To See The Current Filter Resource Usage On The Switch - Allied Telesis x900-24 series Function Manual

How to see the current filter resource usage on the switch

The show switch command outputs a number of counters that display the current usage of
filtering resources. A typical output from this command, and a discussion of each of the
values it outputs, is shown below:

How many filters can you create?
Description
Total number of classifiers/filter rules available in the system.
This is the sum of the rules available on the base system and
the rules available on the IPv6 accelerator.
Number of classifiers currently being used
Number of rules reserved, accounting for block size of 8.
Even though there are only 8 rules in use, there have actually
been 3 blocks of 8 rules allocated from the rule table, as the
rules in the rule table must be allocated in blocks of 8. The
blocks are:
one block on the base system for packets arriving into the
switch via port 1 (which has had a QoS policy applied to it)
one block on the base system for packets arriving in via
any other port
one block allocated on the IPv6 accelerator.
Splitting the rule allocation out on a per-application basis:
2 rules on port 1 for MLD, 2 for MLD on all the other
ports
1 default rule in the IPv6 card
1 hardware filter rule for port 1, and one for all the other
ports
1 QoS rule for port 1
Total number of actions available for hardware filters or QoS
8 actions in use by the 8 rules, and 2 default actions (for
packets that match no rules)
Resource being used by the first device, which is the base
board
Same as the 8 above, except for the one that is on the IPv6
card
Two 8-rule blocks have been allocated on the base system
Splitting the rule allocation out on a per-application basis
2 rules on port 1 for MLD and 2 for MLD on all the other
ports
1 hardware filter rule for port 1, and one for all the other
ports
1 QoS rule for port 1
Total number of rules in the rule table on the base system
