Want to consult the predecessors, I am the network breakdown, Cisco2960 pick what ah, have all the interface corresponding to the upper is Cisco881 is Cisco1841 again, just go to work, also didn't taught me, thank you

CodePudding user response:

First show interface interface type bai and then analyzed one by one

CodePudding user response:

See the directly connected devices is not show CDP nei?

CodePudding user response:

Cisco2960 is a common layer 2 switches, which you can check it through the first show vlan interface in which a vlan, so you can see what kind of cable on the switches in a network segment,
In addition, you can show CDP nei check, the 2960 what cisco equipment, these devices to keep on which the mouth, this command is only applicable to the cisco equipment,

CodePudding user response:

Cisco 881, 1841, all the old tooth, still use ah, on a network without three layer also estimates that more than even the vlan, a vlan must do single-arm routing,

CodePudding user response:

Sh vlan b look at what a vlan and interface classification
Sh int tru view trun mouth and allows vlan
Sh CDP nei view network device name and connection port
See if interface can double up sh IP int b
Sh MAC add to view the MAC and interface connection
When sh arp check MAC corresponds to the IP, individual need to the corresponding terminal a casual ping to learn
Combine these analysis

Old users with network equipment before, haven't changed

Thank you for the great god, cisco certification can recommend learning materials
