Configuring Simple Network Management Protocol traps
5
You can change the holddown time to a value from one second to ten minutes. 
To change the holddown time for SNMP traps, enter a command such as the following at the global 
CONFIG level of the CLI.
BigIron RX(config)# snmp-server enable traps holddown-time 30
The command changes the holddown time for SNMP traps to 30 seconds. The device waits 30 
seconds to allow convergence in STP and OSPF before sending traps to the SNMP trap receiver.
Syntax: [no]snmp-server enable traps holddown-time <secs>
The <secs> parameter specifies the number of seconds (1 – 600).  The default is 60.
Disabling SNMP traps
The device comes with SNMP trap generation enabled by default for all traps. 
By default, all SNMP traps are enabled at system startup.
You can selectively disable one or more of the following traps: 
• SNMP authentication key
• Power supply failure
• Fan failure
• Cold start
• Link up
• Link down
• Bridge new root
• Bridge topology change 
• Locked address violation 
• Module insert
• Module remove
• BGP4
• OSPF
• FSRP
• VRRP
• VRRPE
To stop link down occurrences from being reported, enter the following.
BigIron RX(config)# no snmp-server enable traps link-down
Syntax: [no] snmp-server enable traps <trap-type>
A list of Brocade traps is available in the MIB Reference Guide.
