The snmp-agent community plaintext enable command enables SNMPv1 and SNMPv2c community names to be displayed in plaintext.
The undo snmp-agent community plaintext enable command enables SNMPv1 and SNMPv2c community names to be displayed in ciphertext.
By default, SNMPv1 and SNMPv2c community names are displayed in ciphertext.
Usage scenario
After you run the snmp-agent community plaintext enable command, the community name is displayed in plaintext after you run the snmp-agent community { read | write } community-name command to specify a plaintext community name.
Precautions
The existing community names are not affected after you run the snmp-agent community plaintext enable command. But the configured community names displayed in plaintext will be encrypted and displayed in ciphertext after you run the undo snmp-agent community plaintext enable command.
To ensure the security of community names, enable SNMPv1 and SNMPv2c community names to be displayed in ciphertext.
