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:

Command output	Description
Traffic Control Unit,hardware	Total number of classifiers/filter rules available in the system.
resource usage:	This is the sum of the rules available on the base system and
Total system rule space ... 2048
	the rules available on the IPv6 accelerator.
Total number of rules used .... 8	Number of classifiers currently being used
Total rule space usage ........ 24	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:
	z one block on the base system for packets arriving into the
	switch via port 1 (which has had a QoS policy applied to it)
	z one block on the base system for packets arriving in via
	any other port
	z one block allocated on the IPv6 accelerator.
Number of rules per application:	Splitting the rule allocation out on a per-application basis:
MLD Snooping ................ 4	z 2 rules on port 1 for MLD, 2 for MLD on all the other
	ports
Accel. Card(IPv6) ........... 1
Switch HwFilter ............. 2	z 1 default rule in the IPv6 card
QOS ......................... 1	z 1 hardware filter rule for port 1, and one for all the other
	ports
	z 1 QoS rule for port 1
Total number of actions ... 1024	Total number of actions available for hardware filters or QoS
Number of actions used ........ 10	8 actions in use by the 8 rules, and 2 default actions (for
	packets that match no rules)
Device Resource, device #0:	Resource being used by the first device, which is the base
Number of rules used ........ 7	board
Rule space usage ............ 16
	z Same as the 8 above, except for the one that is on the IPv6
	card
	z Two 8-rule blocks have been allocated on the base system
Number of rules per application:	Splitting the rule allocation out on a per-application basis
MLD Snooping .............. 4	z 2 rules on port 1 for MLD and 2 for MLD on all the other
Switch HwFilter ........... 2
	ports
QOS ....................... 1
Device rule space limit .. 1024	z 1 hardware filter rule for port 1, and one for all the other
	ports
	z 1 QoS rule for port 1
	z Total number of rules in the rule table on the base system
