If you use both SW-MIB and FA-MIB, you may receive duplicate information. You can disable the
FA-MIB, but not the SW-MIB.
You can also use these additional MIBs and their associated traps:
•
FICON-MIB (for FICON environments)
•
SW-EXTTRAP
Includes the swSsn (Software Serial Number) as a part of Brocade SW traps.
For information on Brocade MIBs, see the
Fabric OS MIB Reference
.
For information on the specific commands used in these procedures, refer to the online help or the
Fabric OS Command Reference.
SNMP and Virtual Fabrics
When an SNMPv3 request arrives with a particular username, it executes in the home Virtual
Fabric. From the SNMP manager all SNMPv3 requests must have a home Virtual Fabric that is
specified in the
contextName
field. Whenever the home Virtual Fabric is specified, it will be
converted to the corresponding switch ID and the home Virtual Fabric will be set. If the user does
not have permission for the specified home Virtual Fabric, this request fails with an error code of
noAccess
.
For an SNMPv3 user to have a home Virtual Fabric, a list of allowed Virtual Fabrics, an RBAC role,
and the name of the SNMPv3 user should match that of the Fabric OS user in the local switch
database. SNMPv3 users whose names do not match with any of the existing Fabric OS local users
have a default RBAC role of admin with the SNMPv3 user access control of read/write. Their
SNMPv3 user logs in with an access control of read-only. Both user types will have the default
switch as their home Virtual Fabrics.
The
contextName
field should have the format “VF:
xxx
” where
xxx
is the actual VF_ID, for example
“VF:1”. If the
contextName
field is empty, then the home Virtual Fabric of the local Fabric OS user
with the same name is used. As Virtual Fabrics and Admin Domains are mutually exclusive, this
field is considered as Virtual Fabrics context whenever Virtual Fabrics is enabled. You cannot
specify chassis context in the
contextName
field.
The following example shows how the VF:xx field is used in the snmpwalk command. The snmpwalk
command is executed on the host and it walks the entire MIB tree specified (.1).
#snmpwalk -u admin -v 3 -n VF:4 192.168.176.181 .1
Filtering ports
Each port can belong to only one Virtual Fabric at any time. An SNMP request coming to one Virtual
Fabric can only view the port information of the ports belonging to that Virtual Fabric. All port
attributes are filtered to allow SNMP to obtain the port information only from within the current
Virtual Fabrics context.
Switch and chassis context enforcement
All attributes are classified into one of two categories:
•
Chassis-level attributes
•
Switch-level attributes
