Set SNMP access control as follows. When a command is run, parameter setting information in which specification is omitted is deleted.
When you specify the community, storageSystemName (CLI: storage_system_name), contact, or location parameters for editing SNMP settings, observe the following:
-
Number of characters: Maximum of 180
-
Characters that can be used: Numbers (0 to 9), uppercase alphabet (A to Z), lowercase alphabet (a to z), symbols (! # $ ' ( ) + -.@ _ ` { } ~)
Alternatively, spaces can also be used except for the starting and ending positions, where spaces are not allowed.
When using a DNS server, a storage node caches DNS inquiry results for the time (DNS TTL) set in the DNS server. For this reason, if the content registered in the DNS server (correspondence between the host name and IP address) is changed, the storage node might access an old address during DNS TTL. Therefore, if you have changed the content registered in the DNS server (correspondence between the host name and IP address), wait until the time specified for DNS TTL has passed, and then edit SNMP settings.
