Telnet Service ACL 保護機制

為了提高交換器安全，可以在 交換器上面啟動ACL保護交換器不被一般使用者TELNET，只允許特定的 IP 進來存取

主要差別在於 Comware 7 下在Global 而 Comware 5 下在user-interface

Comware 7設備下法如下

[C]telnet server ?

acl Specify an ACL to control telnet clients' access

dscp Set the Differentiated Services Codepoint (DSCP) value

enable Enable telnet server function

ipv6 IPv6 information

Comware 5 設備下法如下

# Define ACL 2000.

<device> system-view

[device] acl number 2000

[device-acl-basic-2000] rule 1 permit source 10.110.100.52 0

[device-acl-basic-2000] quit

# Reference ACL 2000 on VTY user interface to control Telnet login users.

[device] user-interface vty 0 4

[device-ui-vty0-4] acl 2000 inbound
