SWITCH ADDRESS:
· Config# ip address 192.168.10.2 255.255.255.0
· Config# ip default-gateway 192.168.10.1
DUPLEX MODE:
· Config# interface Ethernet 0/5 – “fastethernet” for 100 Mbps ports
· Config-if# duplex full – also, half | auto | full-flow-control
SWITCHING MODE:
· Config# switching-mode store-and-forward – also, fragment-free
MAC ADDRESS CONFIGS:
· Config# mac-address-table permanent aaab.000f.ffef e0/2 – only this mac will work on this port
· Config# mac-address-table restricted static aaab.000f.ffef e0/2 e0/3
-port 3 can only send data out port 2 with that mac
-very restrictive security
· Config-if# port secure max-mac-count 5 – allows only 5 mac addresses mapped to this port
VLANS:
· Config# vlan 10 name FINANCE
· Config# interface Ethernet 0/3
· Config-if# vlan-membership static 10
TRUNK LINKS:
· Config-if# trunk on – also, off | auto | desirable | nonegotiate
· Config-if# no trunk-vlan 2
-removes vlan 2 from the trunk port
-by default, all vlans are set on a trunk port
CONFIGURING VTP:
· Config# delete vtp – should be done prior to adding to a network
· Config# vtp server – the default is server, also client and transparent
· Config# vtp domain Camp – name doesn’t matter, just so all switches use the same
· Config# vtp password 1234 – limited security
· Config# vtp pruning enable – limits vtp broadcasts to only switches affected
· Config# vtp pruning disable
FLASH UPGRADE:
· Config# copy tftp://192.5.5.5/configname.ios opcode – “opcode” for ios upgrade, “nvram” for startup config
DELETE STARTUP CONFIG:
· Config# delete nvram
