zIntroduction

zTelnet Protection Configuration

1.1 Introduction

The Telnet protection function is used to protect Telnet packets, SNMP packets, and

ICMP packets from the specific source IP addresses in the case of attacks against the

network or high CPU utilization.

Telnet protection comes in global Telnet protection, special ARP Telnet protection, and

default-route Telnet protection. Global Telnet protection is the highest in priority; then

comes special ARPTelnet protection and default-route Telnet protection is the lowest in

priority.

After you configure global Telnet protection, all the Layer-3 interfaces are protected.

You can also configure special ARP Telnet protection to protect specified Layer-3

interfaces. If the default route exists, you can enable special ARP Telnet protection on

the gateway of the network segment where the next hop of the default route resides

through enabling default-route Telnet protection. By default, default-route Telnet

protection is disabled.

Before configuring Telnet protection, you need to enable Telnet, SNMP, and ICMP

protection respectively. You can configure Telnet protection, SNMP protection, and

ICMP protection for only the packets of the specific source IP addresses.

Caution:

After the network address translation (NAT) function is enabled,

zYou cannot configure global Telnet protection.

zYou cannot configure special ARP Telnet protection for the Layer-3 interface where

NAT resides.

zYou cannot configure default-route Telnet protection.
