Chapter 35 Configuring SNMP
Configuring SNMP
Beginning in privileged EXEC mode, follow these steps to configure SNMP on the switch:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
snmp-server engineID {local engineid-string
| remote ip-address [udp-port port-number]
engineid-string}
Configure a name for either the local or remote copy of SNMP.
• The engineid-string is a 24-character ID string with the name
of the copy of SNMP. You need not specify the entire
24-character engine ID if it has trailing zeros. Specify only the
portion of the engine ID up to the point where only zeros
remain in the value. For example, to configure an engine ID of
123400000000000000000000, you can enter this:
snmp-server engineID local 1234
• If you select remote, specify the ip-address of the device that
contains the remote copy of SNMP and the optional User
Datagram Protocol (UDP) port on the remote device. The
default is 162.
Step 3
snmp-server group groupname {v1 | v2c | v3
{auth | noauth | priv}} [read readview]
[write writeview] [notify notifyview] [access
access-list]
Configure a new SNMP group on the remote device.
• For groupname, specify the name of the group.
• Specify a security model:
– v1 is the least secure of the possible security models.
– v2c is the second least secure model. It allows
transmission of informs and integers twice the normal
width.
– v3, the most secure, requires you to select an
authentication level:
auth—Enabl
es the Message Digest 5 (MD5) and the
Secure Hash Algorithm (SHA) packet authentication.
noauth—En
ables the noAuthNoPriv security level. This
is the default if no keyword is specified.
priv—En
ables Data Encryption Standard (DES) packet
encryption (also called privacy).
• (Optional) Enter read readview with a string (not to exceed 64
characters) that is the name of the view in which you can only
view the contents of the agent.
• (Optional) Enter write writeview with a string (not to exceed
64 characters) that is the name of the view in which you enter
data and configure the contents of the agent.
• (Optional) Enter notify notifyview with a string (not to exceed
64 characters) that is the name of the view in which you
specify a notify, inform, or trap.
• (Optional) Enter access access-list with a string (not to exceed
64 characters) that is the name of the access list.
