. SWITCH>(enable) show ip route
Prompt/System name 설정
. SWITCH>(enable) set prompt [hostname]
. SWITCH>(enable) set system name [hostname]

. SWITCH>(enable) set boot system flash slot0:cat6000-sup2k8.7-2-2.bin
. SWITCH>(enable) set boot system flash bootflash:cat6000-sup2k8.7-2-2.bin
. SWITCH>(enable) set boot config-register 0x2102
Tacacs 설정
. SWITCH>(enable) set tacacs server 12.26.109.225 primary
. SWITCH>(enable) set authentication login tacacs enable telnet primary
Logging 설정
. SWITCH>(enable) set logging server 12.52.200.7
. SWITCH>(enable) set logging buffer 500
. SWITCH>(enable) set logging server severity 5
☞ severity는 level 5(notification)로 지정한다.
Snmp 설정
. SWITCH>(enable) set snmp community read-only guest
. SWITCH>(enable) set snmp community read-write master
. SWITCH>(enable) set ip permit enable snmp
. SWITCH>(enable) set ip permit [ip address] snmp
NTP 설정
. SWITCH>(enable) set ntp client enable
. SWITCH>(enable) set ntp server 12.28.250.10
. SWITCH>(enable) set timezone kst 9 0
. SWITCH>(enable) show ntp
Creating an Ethernet VLAN
. SWITCH>(enable) set vlan [vlan_num]
. SWITCH>(enable) show vlan [vlan_num]
Deleting an Ethernet VLAN
. SWITCH>(enable) clear vlan [vlan_num]
Assigning Switch Ports to a VLAN
. SWITCH>(enable) set vlan [vlan_num] [mod_num/port_num]
. SWITCH>(enable) show vlan [vlan_num]
. SWITCH>(enable) show port status [mod_num/port_num]
Port enable/disable
. SWITCH>(enable) set port enable [mod_num/port_num]
. SWITCH>(enable) set port disable [mod_num/port_num]
. SWITCH>(enable) show port state [mod_num/port_num]
Port speed,duplex
. SWITCH>(enable) set port duplex [mod_num/port_num] [auto|half|full]
. SWITCH>(enable) set port speed [mod_num/port_num] [auto|10|100]
. SWITCH>(enable) show port status [mod_num/port_num]
Ether-Channel 설정 (필요시)
. SWITCH>(enable) set port channel [port-list] mode [on/off/auto/desirable]
. SWITCH>(enable) set port channel all distribution mac [both/single]
. SWITCH>(enable) show port channel [mod_num/port_num]
☞ channel mode는 auto-desirable, or on-on으로 설정한다.
Trunk 설정 (필요시)
. SWITCH>(enable) set trunk [mod_num/port_num] [on/off/auto/desirable]
[isl/dot1q/dot10/lane/negotiate]
. SWITCH>(enable) clear trunk [mod_num/port_num] [vlan]
. SWITCH>(enable) show trunk [mod_num/port_num]
☞ trunk-mode는 on으로 설정하고 trunk-type은 isl로 설정한다.
☞ trunk vlan을 제한하거나, 제거시킬때 clear command를 사용한다.
Spanning-tree (PortFast)
. SWITCH>(enable) set spantree portfast [mod_num/port_num] enable
. SWITCH>(enable) show spantree [mod_num/port_num]
☞ forwarding delay (30초)를 생략함으로서 빠른 forwarding stat로 전환가능
☞ 일반 단말포트를 대상으로 enable하며, Switch, hub, oncenturator등의 장비와 연결되는 port에는 반드시 disable 시킨다.
Spanning-tree (Uplinkfast)
. SWITCH>(enable) set spantree uplinkfast enable
. SWITCH>(enable) show spantree uplinkfast
. SWITCH>(enable) set spantree uplinkfast disable
. SWITCH>(enable) clear spantree uplinkfast
☞ blocking port와 root port의 uplink-group를 가진 switch에서 direct-link에
대해서만 uplinkfast를 적용한다.
☞ uplinkfast 삭제시 disable 및 clear를 시켜줌으로써 port-cost에 더해진 3000을 원복할 수 있다. (Default cost, 1Gbps : 4, 100Mbps : 19, 10Mbps : 100)
Spanning-tree (Backbonefast)
. SWITCH>(enable) set spantree backbonefast enable
. SWITCH>(enable) show spantree backbonefast
. SWITCH>(enable) set spantree backbonefast disable
☞ loop을 구성한 모든 switch에 enable 시켜야 하며, 설정시 undirect-link fail시에도Max-aging time을 생략함으로써 Link-up 시간을 단축시킬수 있다.
☞ backbonefast 해제시에는 disable 시킨다.
