7.3.5 SNMP Server Commands
7.3.5.1 show snmp
This command displays SNMP community information.
Six communities are supported. You can add, change, or delete communities. The switch does not have
to be reset for changes to take effect.
The SNMP agent of the switch complies with SNMP versions 1, 2c, and 3 (for more about the SNMP
specification, see the SNMP RFCs). The SNMP agent sends traps through TCP/IP to an external SNMP
manager based on the SNMP configuration (the trap receiver and other SNMP community parameters).
Syntax
show snmp
Default Setting
None
Command Mode
Privileged Exec
Display Message
SNMP Community Name: The community string to which this entry grants access. A valid entry is a
case-sensitive alphanumeric string of up to 16 characters. Each row of this table must contain a
unique community name.
Client IP Address: An IP address (or portion thereof) from which this device will accept SNMP
packets with the associated community. The requesting entity's IP address is ANDed with the Subnet
Mask before being compared to the IP Address. Note: that if the Subnet Mask is set to 0.0.0.0, an IP
Address of 0.0.0.0 matches all IP addresses. The default value is 0.0.0.0
Client IP Mask: A mask to be ANDed with the requesting entity's IP address before comparison with
IP Address. If the result matches with the IP Address then the address is an authenticated IP address.
For example, if the IP Address = 9.47.128.0 and the corresponding Subnet Mask = 255.255.255.0, a
range of incoming IP addresses would match. That is, the incoming IP Address could equal
9.47.128.0 - 9.47.128.255. The default value is 0.0.0.0.
Access Mode: The access level for this community string.
Status: The status of this community access entry.
7.3.5.2 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.
