Usage Guidelines
To use a router as an MLS, you must meet these conditions:
•
The router must be included (either explicitly or automatically) in the MLS-SE.
•
The MLS feature must be enabled in the Catalyst 6500 series switches.
•
Catalyst 6500 series switches must know the MAC-VLAN pairs on the router.
If you enter any of the clear mls statistics commands on a Catalyst 6500 series switch without MLS, this warning message displays:
Feature not supported in hardware.
When you remove an MSM from the Catalyst 6500 series switch, it is removed immediately from the inclusion list and all the MLS entries for the MSM are removed.
Examples
This example shows how to clear IP MLS statistics, including total packets switched and total packets exported (for NDE):
Console> (enable) clear mls statistics
Netflow data export statistics cleared.
This example shows how to clear protocol 17, port 19344 from the statistics collection:

clear mls statistics entry ip [destination ip_addr_spec] [source ip_addr_spec]
[protocol protocol] [src-port src_port] [dst-port dst_port]
clear mls statistics entry ipx destination ipx_addr_spec
Syntax Description
ip
|
(Optional) Specifies IP MLS.
|
ipx
|
(Optional) Specifies IPX MLS.
|
all
|
Purges all matching MLS entries.
|
destination
|
(Optional) Specifies the destination IP address.
|
ip_addr_spec
|
(Optional) Full IP address or a subnet address in these formats: ip_addr, ip_addr/netmask, or ip_addr/maskbit.
|
source
|
(Optional) Specifies the source IP address.
|
protocol protocol
|
(Optional) Specifies additional flow information (protocol family and protocol port pair) to be matched; valid values are from 0 to 255 or ip, ipinip, icmp, igmp, tcp, and udp.
|
src-port src_port
|
(Optional) Specifies the source port IP address; valid values are from 1 to 65535, dns, ftp, smtp, telnet, x (X-Windows), www.
|
dst-port dst_port
|
(Optional) Specifies the destination port IP address; valid values are from 1 to 65535, dns, ftp, smtp, telnet, x (X-Windows), www.
|
ipx_addr_spec
|
Full IPX address or a subnet address in these formats: src_net/[mask], dest_net.dest_node, or dest_net/mask.
|
Defaults
This command has no default settings.
Command Types
Switch command.
Command Modes
Privileged.
Usage Guidelines
If you specify the ip keyword or do not enter a keyword, the command supports IP MLS. If you specify the ipx keyword, the command supports IPX only.
When you remove an MSM from the Catalyst 6500 series switch, it is removed immediately from the inclusion list and all the MLS entries for the MSM are removed.
When entering the IPX address syntax, use the following format:
•
IPX net address—1..FFFFFFFE
•
IPX node address—x.x.x where x is 0..FFFF
•
IPX address—ipx_net.ipx_node (for example 3.0034.1245.AB45, A43.0000.0000.0001)
Up to 16 routers can be included explicitly as MLS-RPs.
To use a router as an MLS, you must meet these conditions:
•
The router must be included (either explicitly or automatically) in the MLS-SE.
•
The MLS feature must be enabled in the Catalyst 6500 series switches.
•
Catalyst 6500 series switches must know the router's MAC-VLAN pairs.
Use the following syntax to specify an IP subnet address:
•
ip_subnet_addr—This is the short subnet address format. The trailing decimal number 00 in an IP address YY.YY.YY.00 specifies the boundary for an IP subnet address. For example, 172.22.36.00 indicates a 24-bit subnet address (subnet mask 172.22.36.00/255.255.255.0), and 173.24.00.00 indicates a 16-bit subnet address (subnet mask 173.24.00.00/255.255.0.0). However, this format can identify only a subnet address of 8, 16, or 24 bits.
•
ip_addr/subnet_mask—This is the long subnet address format. For example, 172.22.252.00/255.255.252.00 indicates a 22-bit subnet address. This format can specify a subnet address of any bit number. To provide more flexibility, the ip_addr is a full host address, such as 172.22.253.1/255.255.252.00.
•
ip_addr/maskbits—This is the simplified long subnet address format. The mask bits specify the number of bits of the network masks. For example, 172.22.252.00/22 indicates a 22-bit subnet address. The ip_addr is a full host address, such as 193.22.253.1/22, which has the same subnet address as the ip_subnet_addr.
A 0 value for src_port and dest_port clears all entries. Unspecified options are treated as wildcards, and all entries are cleared.
If you enter any of the clear mls commands on a Catalyst 6500 series switch without MLS, this message is displayed:
Feature not supported in hardware.
Examples
This example shows how to clear all specific MLS entries:
Console> (enable) clear mls statistics entry ip all
Multilayer switching entry cleared
This example shows how to clear specific IPX MLS entries for a destination IPX address:
Console> (enable) clear mls statistics entry ipx destination 1.0002.00e0.fefc.6000

The clear pbf command does clear the Layer 2 table entries associated with the VLANs (because the MAC address is no longer valid). You must explicitly clear the PBF-enabled VLANs to remove them from NVRAM by entering the clear pbf vlan vlan command.
You can specify a range of VLANs in the CLI.
Examples
This example shows how to clear PBF on VLANs 11 and 12:
Console> (enable) clear pbf vlan 11-12
PBF disabled on vlan(s) 11-12
Related Commands
set pbf vlan

clear qos autoqos
To return the global automatic QoS configuration to the factory default settings, use the clear qos autoqos command.
Syntax Description
This command has no arguments or keywords.
Defaults
This commands has no default settings.
Command Types
Switch command.
Command Modes
Privileged.
Usage Guidelines
QoS ACLs created through the set port autoqos commands are cleared through the global automatic clear qos autoqos command. Also, any policers used by automatic QoS ACLs are cleared.
The global automatic QoS clear command searches for automatic QoS ACL names. The search algorithm looks for names beginning with the following strings:
•
ACL_IP-PHONES (for ciscoipphone)
•
ACL_IP-SOFTPHONE (for ciscosoftphone)
•
ACL_IP-TRUSTCOS (for trust cos)
•
ACL_IP-TRUSTDSCP (for trust dscp)
Any QoS ACL starting with the above strings is considered an automatic QoS ACL and is cleared. If one is found and the QoS ACL is committed and not mapped to a port or a VLAN, it is deleted.
Similarly, the search algorithm looks for aggregate QoS policers starting with this name:
POLICE_SOFTPHONE-DSCP (for ciscosoftphone).
The global clear command searches for aggregate policer names that begin with POLICE_SOFTPHONE-DSCP. If a policer is found, and there is no QoS ACL associated with it, it is deleted. If a policer is found, and there is a QoS ACL associated with it, a warning is displayed indicating the policer is still in use.
Various error conditions can occur when the global clear command is used. If you have properly executed the port-based clear commands before using the global clear command, no error conditions should occur. However, if you execute the global clear command first or have modified the automatic QoS configuration, the following error conditions could occur:
•
Automatic QoS ACLs still mapped to a port or VLAN
The global clear command will not clear automatic QoS ACLs that are still mapped to a VLAN or port. Instead, it displays a warning indicating the name of the QoS ACL still mapped to a port or VLAN.
•
Aggregate policers still in use
If the automatic QoS policers found are still in use (referenced by a QoS ACL), the global clear command does not remove them. Instead, it displays the name of the aggregate policer.
•
Uncommitted automatic QoS ACLs
The global clear command only removes committed automatic QoS ACLs; it ignores uncommitted automatic QoS ACLS.
Examples
This example shows how to return the global automatic QoS configuration to the factory default settings:
Console> (enable) clear qos autoqos
Its highly recommended to execute clear port autoqos commands prior
to the global clear command:
clear port qos <mod/port> autoqos
Do you want to continue (y/n) [n]? y

Command Types
Switch command.
Command Modes
Privileged.
Usage Guidelines
Policing is the process by which the switch limits the bandwidth consumed by a flow of traffic. Policing can mark or drop traffic.
You cannot clear an entry that is currently being used in an ACE. You must first detach the ACEs from the interface.
You cannot use the all keyword if a microflow rate limit is currently being used in an ACE.
The normal and excess keywords are supported on systems configured with the Supervisor Engine 2 with Layer 3 Switching Engine II (PFC2) only. With these keywords, you can specify a map for the normal rate and one for the excess rate. Because this selection is optional in the CLI, the default (unspecified) action is to apply the given map to the normal rate only.
Examples
This example shows how to clear a specific microflow policing rule:
Console> (enable) clear qos policer microflow my_micro

clear trunk
To restore a trunk port to its default trunk type and mode or to clear specific VLANs from the allowed VLAN list for a trunk port, use the clear trunk command.
clear trunk mod/port [vlans]
Syntax Description
mod/port
|
Number of the module and the port on the module.
|
vlans
|
(Optional) Number of the VLAN to remove from the allowed VLAN list; valid values are from 1 to 4094.
|
Defaults
For all ports except Multilayer Switch Module (MSM) ports, the default is auto negotiate. For MSM ports, the default is off negotiate mode.
Command Types
Switch command.
Command Modes
Privileged.
Usage Guidelines
If you specify VLANs, those VLANs are removed from the list of VLANs allowed on the trunk. Default VLANs cannot be cleared on the trunk.
Traffic for the removed VLANs are not forwarded over a trunk port. To add VLANs that you have removed, use the set trunk mod/port vlans command.
If you are trying to clear extended-range VLANs and sufficient space in NVRAM is not available, a warning message displays and the command fails.
Examples
This example shows how to clear VLANs 200 through 500 from the trunk port on port 2 of module 1:
Console> (enable) clear trunk 1/2 200-500
Removing Vlan(s) 200-500 from allowed list.
Port 1/2 allowed vlans modified to 1-199,501-1000.
This example shows the output if you attempt to clear a trunk when not enough NVRAM space is available:
Console> (enable) clear trunk 2/18 1030-1999
Failed to clear extended range vlans from allowed list.
Not enough NVRAM space. Use the `set trunk' command to restore
some existing entries to the default value.

|
mod
|
Number of the module.
|
Defaults
This command has no default settings.
Command Types
Switch command.
Command Modes
Privileged.
Usage Guidelines
Follow these guidelines for deleting VLANs:
•
When you delete a normal-range Ethernet VLAN in VTP server mode, the VLAN is removed from all switches in the same VTP domain.
•
When you delete a normal-range VLAN in VTP transparent mode, the VLAN is deleted only on the current switch.
•
You can delete an extended-range VLAN only on the switch where it was created.
When you clear a VLAN, all ports assigned to that VLAN become inactive. However, the VLAN port assignments are retained until you move the ports to another VLAN. If the cleared VLAN is reactivated, all ports that are still configured on that VLAN are also reactivated. A warning is displayed if you clear a VLAN that exists in the mapping table.
When you clear a private VLAN (primary, isolated, or community), the ports are set to inactive and are not assigned to any VLAN. The private VLAN mappings for the selected VLAN are also cleared. ACL to VLAN mappings are also deleted.
Examples
This example shows how to clear existing VLAN 4000 from a management domain:
Console> (enable) clear vlan 4000
This command will de-activate all ports on vlan 4
in the entire management domain
Do you want to continue(y/n) [n]? y
