2. For each trap recipient, configure the parameters as follows:
• Community Name — Up to 32 alphanumeric characters. The 
community name is incorporated into SNMP trap messages to 
ensure against unauthorized viewing or use.
• Write Authorization — Is enabled if the box is checked. (The 
default is disabled.) Click the checkbox to add or remove a 
checkmark
When write authorization is enabled, a management 
workstation user can change sysContact, sysName, and 
sysLocation SNMP variables.
• Trap Recipient — IP address or DNS host name of the SNMP 
management workstation, up to 64 alphanumeric characters. 
EMC recommends using the IP address.
• UDP Port Number — The default user datagram protocol 
(UDP) port number for trap recipients is 162. To override this 
port number, click the Advanced option. The dialog box 
expands to show a UDP Port Number
 column.
Enter a decimal port number in the associated UDP Port 
Number field to override the default value.
