Access Mode
The access level for this community string.
Status
The status of this community access entry.
show snmptrap
This command displays SNMP trap receivers. Trap messages are sent across a network to an
SNMP Network Manager. These messages alert the manager to events occurring within the switch
or on the network. Six trap receivers are simultaneously supported.
Format
show snmptrap
Mode
Privileged EXEC
SNMP Trap Name
The community string of the SNMP trap packet sent to the trap
manager. This may be up to 16 alphanumeric characters. This
string is case sensitive.

The IP address to receive SNMP traps from this device. Enter
four numbers between 0 and 255 separated by periods.
Status
A pull down menu that indicates the receiver's status (enabled or
disabled) and allows the administrator/user to perform actions on
this user entry:
Enable
- send traps to the receiver
Disable
- do not send traps to the receiver.
Delete
- remove the table entry.
show trapflags
This command displays trap conditions. Configure which traps the switch should generate by
enabling or disabling the trap condition. If a trap condition is enabled and the condition is detected,
the switch's SNMP agent sends the trap to all enabled trap receivers. The switch does not have to
be reset to implement the changes. Cold and warm start traps are always generated and cannot be
disabled.
Format

privileged level. The length of name can be up to 16 case-sensitive characters.
Note:
Community names in the SNMP community table must be unique. When making multiple
entries using the same community name, the first entry is kept and processed and all duplicate
entries are ignored.
Default
Two default community names: Public and Private. You can
replace these default community names with unique identifiers
for each community. The default values for the remaining four
community names are blank.

snmp-server community ipaddr
This command sets a client IP address for an SNMP community. The address is the associated
community SNMP packet sending address and is used along with the client IP mask value to
denote a range of IP addresses from which SNMP clients may use that community to access the
device. A value of 0.0.0.0 allows access from any IP address. Otherwise, this value is ANDed with
the mask to determine the range of allowed client IP addresses. The name is the applicable
community name.
Default
0.0.0.0
Format
snmp-server community ipaddr
<ipaddr> <name>
Mode
Global Config
no snmp-server community ipaddr
This command sets a client IP address for an SNMP community to
0.0.0.0
. The name is the
applicable community name.

Mode
Global Config
snmp-server community ipmask
This command sets a client IP mask for an SNMP community. The address is the associated
community SNMP packet sending address and is used along with the client IP address value to
denote a range of IP addresses from which SNMP clients may use that community to access the
device. A value of 255.255.255.255 will allow access from only one station, and will use that
machine's IP address for the client IP Address. A value of 0.0.0.0 will allow access from any IP
address. The name is the applicable community name.
Default
0.0.0.0
Format
snmp-server community ipmask <
ipmask> <name>
