show lda
To display the ASLB configuration information, use the show lda command.

[protocol protocol] [src-port src_port] [dst-port dst_port]Syntax Description
Defaults
The default displays MLS entry information in long format.
Command Types
Switch command.
Command Modes
Normal.
Usage Guidelines
This command is supported only on switches configured with the Supervisor Engine 1 with Layer 3 Switching Engine WS-F6K-PFC (Policy Feature Card).
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 value, use the full IP address or a subnet address in one of the following formats: ip_addr, 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:
•
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 with a length of 8, 16, or 24 bits.
•
•
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 no keywords or variables, all entries are displayed.
