5초,1분,5분 동안 라우터 CPU 의 로드가 몇 퍼센트인지를 나타내줍니다.

5. show protocols

Router에서 수행되는 OSI 3 Layer protocol들의 상태를 나타내줍니다.
  Ex)   IP,  DECnet,  IPX,  AppleTalk … protocols

ROUTER#show  protocols
Global values:
  Internet Protocol routing is enabled
  Appletalk routing is enabled
  Novell routing is enabled
Ethernet0/0 is up, line protocol is up
Internet address is 10.1.1.3/24
AppleTalk address is 53.129, zone MACINTOSH
Ethernet0/1 is up, line protocol is up
Internet address is 10.2.1.2/24
Novell address is 150.0060.474d.3d03
Ethernet0/2 is up, line protocol is up
Internet address is 10.3.1.1/24
Ethernet0/3 is administratively down, line protocol is down
Serial1/0 is up, line protocol is down
  Internet address is 10.4.1.10/30

위 예에서 보듯이 각 포트(이더넷,시리얼등)의 ip 주소와 up,down 상태를 간략히 보여주
고 있습니다. 이 명령어의 옵션으로는 다음과 같습니다.

Ethernet  port-number          : 이더넷 포트를 보여줌
Serial     port-number          : 시리얼 포트를 보여줌

6. show ip route

N/W address에 대한 Routing table의 Routing 정보를 보여줍니다.
이 명령어는 같은 세그먼트안에 있는 정보는 보여주지 않습니다. 왠지 아시겠습니까?
라우터의 기능을 잘 생각해보시면 감 잡히시겠죠? ^^;

ROUTER#show  ip  route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default
       U - per-user static route

Gateway of last resort is 88.1.26.200 to network 0.0.0.0

     128.128.0.0/16 is subnetted, 1 subnets
S       128.128.128.0 [1/0] via 10.10.1.50
I    203.248.49.0/24 [100/180681] via 10.5.1.2, 00:00:03, Ethernet0/1
                     [100/180681] via 10.2.1.3, 00:00:03, Ethernet0/0
. . . . . . . . . . . . . .  .  .  .  .



show  ip  route  [ IP network address / IP address ]  
: 특정 N/W address나 IP address의 Routing 정보를 보여줍니다.
