Snmpv1 And V2C Access To The Switch; Snmpv3 Access To The Switch - HP Aruba JL253A Management And Configuration Manual

Click on software updates, then MIBs.

SNMPv1 and v2c access to the switch

SNMP access requires an IP address and subnet mask configured on the switch. If you are using DHCP/Bootp to
configure the switch, ensure that the DHCP/Bootp process provides the IP address.
Once an IP address is configured, the main steps for configuring SNMPv1 and v2c access management features
are:
Procedure
1. Configure the appropriate SNMP communities. (See SNMPv3 communities on page 191.)
2. Configure the appropriate trap receivers.
In some networks, authorized IP manager addresses are not used. In this case, all management stations using
the correct community name may access the switch with the View and Access levels that have been set for that
community. If you want to restrict access to one or more specific nodes, you can use the switch's IP Authorized
Manager feature. (See the access security guide for your switch.)
CAUTION: If network management security is a concern, Hewlett Packard Enterprise recommends
that you change the write access for the "public" community to "Restricted."

SNMPv3 access to the switch

SNMPv3 access requires an IP address and subnet mask configured on the switch. (See "IP Configuration" on
page 8-2.) If you are using DHCP/Bootp to configure the switch, ensure that the DHCP/Bootp process provides
the IP address. (See "DHCP/Bootp Operation".)
Once you have configured an IP address, the main steps for configuring SNMPv3 access management features
are the following:
Procedure
1. Enable SNMPv3 for operation on the switch (see Enabling SNMPv3 on page 186).
2. Configure the appropriate SNMP users (see SNMPv3 users on page 187).
3. Configure the appropriate SNMP communities (see SNMPv3 communities on page 191).
4. Configure the appropriate trap receivers (see SNMP notifications on page 194).
In some networks, authorized IP manager addresses are not used. In this case, all management stations using
the correct User and community name may access the switch with the View and Access levels that have been set
for that community. If you want to restrict access to one or more specific nodes, you can use the IP Authorized
Manager feature for the switch. (See the access security guide for your switch.)
SNMP version 3 (SNMPv3) adds some new commands to the CLI for configuring SNMPv3 functions. To enable
SNMMPv3 operation on the switch, use the snmpv3 enable command. An initial user entry will be generated
with MD5 authentication and DES privacy.
You may (optionally) restrict access to only SNMPv3 agents by using the snmpv3 only command. To restrict
write-access to only SNMPv3 agents, use the snmpv3 restricted-access command.
