    Verifying SIP ALG Configurations

    Verifying SIP ALG

    Purpose

    Verify SIP ALG verification options.

    Action

    From the CLI, enter the show security alg sip ? command.

    user@host> show security alg sip ?
    Possible completions:
      calls                Show SIP calls
      counters             Show SIP counters
      rate                 Show SIP rate
    

    Meaning

    The output shows a list of all SIP verification parameters. Verify the following information:

    • Calls—Lists all SIP calls.
    • Counters—Provides counters of response codes for each SIP request method and error type.
    • Rate—Provides speed and periodicity of SIP signaling messages.

    Verifying SIP ALG Calls

    Purpose

    Display information about active calls.

    Action

    From the J-Web interface, select Monitor>ALGs>SIP>Calls. Alternatively, from the CLI, enter the show security alg sip calls command.

    user@host> show security alg sip calls
    Total number of calls: 1
           Call ID: 47090a32@30.2.20.5
    			Method: INVITE
              

    Meaning

    The output shows a list of all active SIP calls. Verify the User Agent Server (UAS) call ID and local and remote tags, and the state of the call.

    Verifying SIP ALG Call Details

    Purpose

    Display address and SDP about active calls.

    Action

    From the J-Web interface, select Monitor>ALGs>SIP>Details. Alternatively, from the CLI, enter the show security alg sip calls detail command.

    user@host> show security alg sip calls detail
    Total number of calls: 1
           Call ID    : 47090a32@30.2.20.5
    Method   : INVITE
      State    : SETUP
      Group ID : 24575
                  

    Meaning

    The output provides details about all active SIP calls. Verify the following information:

    • The total number of calls, their ID and tag information, and state
    • Remote group ID
    • The IP addresses and port numbers and SDP connection and media details

    Verifying SIP ALG Counters

    Purpose

    Display information about SIP counters.

    Action

    From the J-Web interface, select Monitor>ALGs>SIP>Counters. Alternatively, from the CLI, enter the show security alg sip counters command.

    user@host> show security alg sip counters
    Method         T       1xx       2xx       3xx       4xx       5xx       6xx

    Meaning

    The output provides a count of all SIP response codes transmitted and received, and of SIP errors. Verify the following information:

    • A count of transmissions of response codes for each SIP request method
    • A count of all possible error types

    Verifying the Rate of SIP ALG Messages

    Purpose

    Display information about SIP message rate.

    Action

    From the J-Web interface, select Monitor>ALGs>SIP>Rate. Alternatively, from the CLI, enter the show security alg sip rate command.

    user@host> show security alg sip rate
    CPU ticks per microseconds is 3735928559
        Time taken for the last message is 0 microseconds
        Total time taken for 0 messages is 0 microseconds(in less than 10 minutes)
        Rate: 3735928559 messages/second
    

    Meaning

    The output provides information about CPU usage for messages, and speed and periodicity of SIP signaling messages. Verify the following information:

    • CPU ticks per US
    • Passage time for last message, for all messages, and the rate at which messages transit the network
