SNMP Read Access
SNMP provides standard commands that allow a client to read SNMP data. The PNC supports all of
these commands.:
GET
GETNEXT
GETBULK
The SNMP Community strings supported for read access are:
public
pub
icmp
private
priv
These community strings are fixed and cannot be changed.
SNMP Write Access
SNMP should not be used to change parameters on the PNC module. The SNMP SET command
succeeds for the variables in some MIBs/groups, but fails for the variables in other MIBs/groups.
Changes made using SNMP SET only change the SNMP variable itself, do not affect the PNC
operation, and are not saved across a power-cycle or restart. For example, setting the sysName
variable from the System Group does not change the PNC
’s device name.
MIB-II Groups Supported
The PNC supports all of the mandatory values in the following groups of the MIB-II specification:
System group
Interfaces group
IP group
ICMP group
TCP group
UDP group
Transmission group (802.3 Ethernet subset)
SNMP group
The EGP group and Address Translation group of MIB-II are not supported.
