SIP SLB over TCP
1
Use the server sip tcp max-tcp-transaction-limit command to limit the maximum number of TCP
transactions.
ServerIronADX(config)#server sip tcp max-tcp-transaction-limit 200,000
Syntax: [no] server sip tcp max-tcp-transaction-limit #-of-transactions
The #-of-transactions is the concurrent SIP transactions that a ServerIron ADX can manage. Enter
10 - 300,000 for #-of-transactions. The default value is 100,000.
The command should adjust the default number of concurrent SIP transactions supported on a
local barrel processor (BP). Normally, the default value is more than sufficient. Changing this value
is not recommended.
Real server commands for SIP over TCP
The commands in this section are entered under the SIP real server configuration level.
Use the sip max-tcp-connections command to specify the maximum number of SIP connections
allowed for a real server.
ServerIronADX(config-rs1)#sip max-tcp-connections 15
Syntax: [no] sip max-tcp-connections #-of-connections
The #-of-connections can be from 1 through 64 connections. The default is 64 for connection
reuse cases (source NAT or non-source NAT). For non-connection reuse cases, the default value is
determined by the value configured for the max-conn command.
NOTE
This command takes precedence over the server sip tcp max-client-tcp-connections and server sip
max-server-tcp-connections (global) commands.
Use the sip enable-tcp-connection-reuse command to enable server-side connection reuse when
source NAT is not configured.
ServerIronADX(config-rs1)#sip enable-tcp-connection-reuse
Syntax: [no] sip enable-tcp-connection-reuse
Use the sip alternative-server-ip command to specify an alternate real server IP address for the SIP
real server. This is the IP address that the real server will use to send out SIP requests and
responses. This configuration is required for those SIP servers that may use an IP address other
than the configured real server IP address. This configuration helps a ServerIron ADX to identify the
traffic as real server traffic.
ServerIronADX(config-rs-sip)#sip alternative-server-ip 10.120.5.34
Syntax: [no] sip alternative-server-ip alternate-ip
The alternate-ip variable is the alternate real server IP address.
