- IOS: Create a VLAN
- Change vlan configuration:
switchport mode access, switchport access vlan 4545
- Cisco IOS: enable an interface:
conf t
,int XXXXXX
no shutdown
- Cisco IOS DHCP Server configuration
- Configure public RSA key authentication:
ip ssh pubkey-chain
- Cisco IOS logging
Activities[edit]
- Read Cisco IOS command reference: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fundamentals/command/Cisco_IOS_Configuration_Fundamentals_Command_Reference.pdf
- Read Cisco IOS Cheat Sheet: https://www.netwrix.com/cisco_commands_cheat_sheet.html
- Configure a user with public key access Configure public RSA key authentication
- Associate a user with default higher privileges using
username
command - Create a new VLAN
- Use ansible:
ansible-galaxy install ansible-network.cisco_ios
