Entering the destination keyword specifies the entries matching the destination IP address specification, entering the source keyword specifies the entries matching the source IP address specification, and entering an ip_addr_spec can specify a full IP address or a subnet address. If you do not specify a keyword, it is treated as a wildcard, and all entries are displayed.
When entering the ip_addr_spec, use the full IP address or a subnet address in one of the following formats: ip_addr or ip_addr/netmask or ip_addr/maskbit.
Entering the destination keyword specifies the entries matching the destination IP address specification, entering the source keyword specifies the entries matching the source IP address specification, and entering an ip_addr_spec can specify a full IP address or a subnet address. If you do not specify a keyword, it is treated as a wildcard, and all entries are displayed.
Use the following syntax to specify an IP subnet address:
If you have disabled the ASLB feature, you can view the last configuration using the show lda uncommitted command.
The short | long options give the flexibility to display the output in regular (80 characters in width) or wide screen.
If you enter the show lda mls entry or the show lda mls statistics entry command with with no keywords or variables, all entries are displayed.

If you enter show mls command with no arguments, general IP MLS information and all IP MLS-RP information displays.
A value 0 for src_port and dst_port means "don't care."
Entering the destination keyword specifies the entries matching the destination IP address specification, entering the source keyword specifies the entries matching the source IP address specification, and entering an ip_addr_spec can specify a full IP address or a subnet address. If you do not specify a keyword, it is treated as a wildcard, and all entries are displayed.
Use the following syntax to specify an IP subnet address:
The [long | short] option gives the flexibility to display the output in regular (80 characters in width) or wide screen.
Dashes may be displayed for some fields if the fields are not applicable to the type of flow mask.
If the MSFC is placed on a supervisor engine installed in slot 1, then the MSFC is recognized as module 15. Otherwise, if the supervisor engine is installed in slot 2, the MSFC is recognized as module 16.

If you enter the show mls multicast commands on Catalyst 6000 family switches without MLS, this warning message displays:
This feature is not supported on this device.
If you enter the show mls multicast entry commands with no arguments, all the MLS entries for multicast displays.
If DNS is disabled, no name can be specified or shown.
Entering the vlan keyword specifies the VLAN entries matching this address specification, and entering an ip_addr can specify a full IP address or a subnet address. Entering the group keyword specifies the group entries matching this IP address specification. If you do not specify a keyword, it is treated as a wildcard, and all entries are displayed.
A warning message is displayed if the Layer 2 multicast protocol is disabled when the MMLS feature is running.
If the MSFC is placed on a supervisor engine installed in slot 1, then the MSFC is recognized as module 15. Otherwise, if the supervisor engine is installed in slot 2, the MSFC is recognized as module 16.
