CAS Mode IP Addressing Considerations

2. Cisco highly recommends replacing default password(s) with “strong” passwords (at least 8 characters long, 

comprised of a combination of two characters from each of the upper- and lower-case letters, numbers, and special 
characters categories)

Table 4

CAS Modes— IP addressing Considerations 

CAS Mode

Comments 

Real-IP 

•

The trusted (eth0) and untrusted (eth1) interfaces of the CAS must be on 
different subnets.

•

Add static routes on the L3 switch or router to route traffic for the managed 
subnets to the trusted interface of the respective CASs.

•

If using DHCP relay, make sure the DHCP server has a route back to the 
managed subnets.

NAT (testing 
only)

Note: NAT is not supported for production deployments

•

The trusted (eth0) and untrusted (eth1) interfaces of the CAS must be on 
different subnets.
