思科CGR2010端口参考

简介

本文档介绍Cisco CGR2010平台用于应用和网内通信的TCP和UDP端口。

默认端口

Cisco CGR2010默认启用以下端口：

Router#show control-plane host open-ports
Active internet connections (servers and established)
Prot               Local Address             Foreign Address                  Service    State
 tcp                        *:23                         *:0                   Telnet   LISTEN


Router#

如果路由器中启用了SSH，则端口22在CGR 2010中打开：

Router#show control-plane host open-ports
Active internet connections (servers and established)
Prot               Local Address             Foreign Address                 Service    State
 tcp                        *:22                         *:0              SSH-Server   LISTEN
 tcp                        *:23                         *:0                  Telnet   LISTEN

使用Nmap检验路由器中启用的端口。

C:\Program Files (x86)\Nmap>nmap -sS -p1-10000 10.31.126.137
Starting Nmap 7.70 ( https://nmap.org ) at 2018-12-06 20:05 Central Standard Time (Mexico)
Nmap scan report for 10.31.126.137
Host is up (0.0054s latency).
Not shown: 9998 closed ports
PORT STATE SERVICE
22/tcp open ssh
23/tcp open telnet

Nmap done: 1 IP address (1 host up) scanned in 14.23 seconds

C:\Program Files (x86)\Nmap>

当交换机模块安装在CGR2010上时，路由器会打开端口2003、4003、6003和9003。看看表。

C:\Program Files (x86)\Nmap>nmap -sS -p1-10000 10.31.126.137
Starting Nmap 7.70 ( https://nmap.org ) at 2018-12-06 20:22 Central Standard Time (Mexico)
Nmap scan report for 10.31.126.137
Host is up (0.0067s latency).
Not shown: 9994 closed ports
PORT STATE SERVICE
22/tcp open ssh
23/tcp open telnet
2003/tcp open finger
4003/tcp open pxc-splr-ft
6003/tcp open X11:3
9003/tcp open unknown

Nmap done: 1 IP address (1 host up) scanned in 12.54 seconds

C:\Program Files (x86)\Nmap>
