I am a Cisco beginner and i would like to know how can i do an ISP failover.
My set up
Int 0/0 WAN
Int 0/1 Inside
Int 0/2.2 Voice Vlan120
Int 0/2.31 Wifi Vlan160
Int 0/3 SIP
MGMT Failover to secondary Firewall.
I would like to add our backup ISP to it, as you can see we have ran out of ports on the ASA. is there a way we can trunk or tunnel from one of the switch ports to run a ping and if primary ISP fails the backup ISP port becomes active?
If you can patch both WAN ports into a switch that can speak VLANs (dot1q) and trunk them to int 0/0 and create subinterfaces as you've done with int0/2 and tag correct VLAN, that will get round your lack of ports.
To failover between WAN links look at IP SLA such as below.
1. Log into CLI of DNAC:
ssh maglev@< DNAC appliance IP> -p 2222
2. Run this curl command to get token to get member id:
curl -X POST -u admin:<admin user password> -H -V https://<CLUSTER-IP>/api/system/v1/identitymgmt/token
