Example 42 Unavailable resources
The resource usage on a 3500yl switch configured for ACLs, QoS, RADIUS-based
authentication, and other features:
• The "Rules Used" columns show that ACLs, VT, mirroring, and other features
(for example, Management VLAN) have been configured globally or per-VLAN,
because identical resource consumption is displayed for each port range in
the switch. If ACLs were configured per-port, the number of rules used in each
port range would be different.
• The switch is also configured for VT and is either blocking or throttling routed
traffic with a high rate-of-connection requests.
• Varying ICMP rate-limiting configurations on ports 1 to 24, on ports 25 to 48,
and on slot A, have resulted in different meter usage and different rule usage
listed under QoS. Global QoS settings would otherwise result in identical
resource consumption on each port range in the switch.
• There is authenticated client usage of IDM resources on ports 25 to 48.
