Verifying SIP ALGs
Purpose
Display 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 callscommand.
user@host> show security alg sip callsTotal 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
detailTotal 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.

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 rateCPU 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
