Resource Monitor Window
This window is only available for Catalyst 2950 switches that run the enhanced
software image. It appears when you choose Reports > Resource Monitor
on the menu bar. You can also click here
to launch it. You can also launch this window from an error dialog, which is
displayed when you are unable to configure access groups or create policy maps
because of mask limitations.
The window presents three views of how resources are used, each accessed by
a radio button:
- Masks, to see the information by mask number
- Interfaces, to see the information by interface
type and number
- Usage, to see the information by ACL or QoS
policy
Begin by selecting a device from the Host Name list. The device that
you select determines the contents of the window.
Notes:
- If no mask is in use on the selected device, you see this message in place
of the radion buttons and resource report: All the masks are available.
- If you attach an ACL or a QoS policy to an interface or detach either from
an interface while the window is open, click Refresh, and the window
displays your changes.
When you finish viewing the window, click OK.
Each mask that is used on the device is shown with a system-assigned number
in an expandable heading. Beneath an expanded heading are these entries:
- The mask type. The type is QoS if the mask is used by a QoS policy.
Otherwise, the type is Security.
- The fields in the packet header that the mask refers to.
- A policy map if the mask type is QoS, or an ACL name (or
number) if the mask type is Security.
Note: This entry does not appear if no ACLs with the mask are attached
to an interface.
Each interface with an attached ACL, an attached QoS policy, or both is shown
by its type and number in an expandable heading. Beneath an expanded heading
are these entries:
- The system-assigned number of the mask that belongs to the attached ACL.
- The mask type. The type is QoS if the mask is used by a QoS policy
or Security if the mask is used by an ACL.
- The fields in the packet header that the mask refers to.
- The name (or number) of the ACL or QoS policy map, or both, that
is attached to this interface.
The type and number (or name) of each attached ACL or QoS policy is shown in
an expandable heading. Beneath an expanded heading is an entry showing the interfaces
that the ACL or QoS policy is attached to. This entry also expands to show these
subentries:
- The system-assigned number of the mask that is used by the ACL
or QoS policy.
- The mask type. The type is QoS if the mask belongs to an ACL that
is associated with a QoS class. Otherwise, the type is Security.
- The fields in the packet header that the mask refers to.
