SNMP informs
The SNMP Informs dialog box allows you to enable or disable informs on informs-capable products.
SNMP traps are unreliable because the receiver does not send any acknowledgment when it
receives a trap. The sender cannot determine if the trap was received. However, an SNMP manager
that receives an inform request acknowledges the message with an SNMP response protocol data
unit (PDU). If the manager does not receive an inform request, it does not send a response. If the
sender (switch) never receives a response, the inform request can be sent again. For this reason,
informs are more likely to reach their intended destination.
When using informs, the engine ID must be set to correspond to the management engine IP
address to authenticate the inform request. When informs are enabled, the sender sends initial
informs request for engine ID discovery from any of its ephemeral ports (ranging from 32768 to
65535) to port 161 on the Management server. The sender receives the acknowledgement of the
informs requests on these ephemeral ports. If there is a firewall between the Management
application and the switches, the ephemeral ports must be open for SNMP informs to work.
Enabling or disabling SNMP informs
1. Select Monitor > SNMP Setup > Informs.
The SNMP Informs dialog box displays.
2. Select a product group from the Fabric / Products list.
The products display in the SNMP Informs Capable Products list, where you can determine if
the product’s status is enabled or disabled.
3. Select a product in the SNMP Informs Capable Products list and click the appropriate Action
button, depending on whether you want to enable or disable SNMP informs for that product.
4. Click OK.
Syslogs
Use the Options dialog box to automatically register the Management application server as the
syslog recipient on all managed SAN and IP products. The syslog listening port number is 514 by
default. If you change the port number from 514, auto-registration is disabled.
NOTE
The Brocade 6910 is not listed in the Syslog Recipient dialog box.
