1 ICND IOS CLI Study Guide (CCNA) SWITCH CONFIGURATION STP (Change Options): 2. spanning-tree mode rapid-pvst [pvst] OR [mst] 3. Assign PortFast and/or BPDU Guard (sub-interface cmd): a. spanning-tree portfast b. spanning-tree bpduguard enable 4. spanning-tree vlan # cost # 5. spanning-tree vlan # priority ##### a. spanning-tree vlan # root primary [secondary] 6. Check STP: a. show spanning-tree {vlan #] b. show spanning-tree root Etherchannel: 2. int range f0/5 7 (or single Interface) 3. channel-group 1 mode on 4. NOTE: if using PAgP or LACP, use mode auto, desirable, active, or passive 5. Verify: show run int po# OR show etherchannel # summary Troubleshoot STP: 1. show spanning tree [vlan #] 2. show mac address-table 3. show spanning tree root Troubleshoot Etherchannel: 1. show int PO# 2. show etherchannel # summary 3. sho ip int status ROUTER CONFIGURATION Config Serial Interface: 2. int s0/1/0 3. encapsulation ppp [hdlc] 4. ppp authentication chap (opt) a. username R2 password pwd (R1) b. username R1 password pwd (R2) 4. no shut 5. Verify: show int s0/1/0 OR show int brief OR show controllers Load New IOS Image: 1. copy tftp flash (prompted for TFTP server & IOS filename) 2. Verify file copy: show flash 3. config t 4. Boot to new image: boot system flash:imagefilename.bin 5. copy run start 6. reload 7. Verify: show version Cisco License Install: 1. show license udi 2. go to Cisco License Portal 3. Enter UDI # & PAK purchase # 4. Download license file to Flash 5. Connect Flash drive to device 6. license install usbflash1:ftx### ##P_#########.lic 7. reload 8. Verify: show license [feature] 9. To enable a IOS feature set: a. license boot module c2900 technology-package securityk9 Configure Multi-Area OSPF: 2. router ospf 1 3. router-id #.#.#.# (e.g.) 4. int f0/1 5. ip ospf 1 area 0 6. int f0/0 7. ip ospf area Other options: a. ip ospf cost # (sub-int cmd) b. maximum-paths # (sub-rtr cmd)

2 c. passive-interface f0/2 (sub- Rtr cmd) d. bandwidth (sub-int in Kbps) e. auto-cost reference-bandwidth #### (sub-rtr cmd in Mbps) 8. Verify: show ip ospf neighbor ; show ip ospf database ; show ip route ; show ip protocol Configure EIGRP: 2. router eigrp 1 (A/S number) 3. no auto-summary 4. eigrp router-id #.#.#.# 5. network #.#.#.# #.#.#.# (Subnet & Wildcard Mask) 6. Other options: a. bandwidth # (sub-int in Kbps) b. maximum-paths (sub-rtr cmd) c. variance (sub-rtr cmd) d. ip hello-interval eigrp # (sub-int cmd) e. ip hold-time eigrp # (sub-int cmd) f. delay # (sub-int cmd) g. passive-interface (sub-int) Confgure VRRP: 3. vrrp # (# = 0-255) 4. vrrp priority # (default is 100; higher = active Router) 5. vrrp # preempt 6. go to next Rtr & config the same 7. Verify: show vrrp Configure HSRP: 3. standby # ip (# = 0-255) 4. standby priority # (default is 100; higher = active Router) 5. standby # preempt 6. go to next Rtr & config the same 7. Verify: show standby [brief] Configure GLBP: 3. glbp # ip (# = 0-255) 4. glbp priority # (default is 100; higher = active Router) 5. go to next Rtr & config the same 7. Verify: show glbp [brief]

3 Configure Syslog: 1. Console enable: logging console 2. Server enable: logging #.#.#.# 3. logging trap 4 (set Severity level) 4. Verify: show logging (& view Logging Server for msgs) Configure SNMP: 1. ip access-list standard ACL-SNMP 2. permit host #.#.#.# 3. snmp-server community Pwd RW ACL- SNMP Configure Frame Relay: 1. One Subnet: c. ip address #.#.#.# #.#.#.# d. encapsulation frame-relay (NOTE: no mode = cisco default, otherwise use ietf ) 1) frame-relay map ip #.#.#.# ietf (to map different mode for a Rtr that needs to use other than Cisco default) e. no shut f. Options: 1) frame-relay lmi-type [ansi] 2) frame-relay map ip #.#.#.# ## broadcast (Remote Rtr IP; local Rtr DLCI) 2. Point-to-Point c. encapsulation frame-relay d. int s0/0/0.1 point-to-point e. ip address #.#.#.# #.#.#.# f. frame-relay interface-dlci # g. no shut h. int s0/0/0.2 point-to-point i. ip address #.#.#.# #.#.#.# j. frame-relay interface-dlci # k. no shut 3.
