As part of a vWAAS deployment on a 3945-ISR-G2, my objective was to access the UCS-E server, initially the CIMC interface for the install of ESXi and then vWAAS, via the /29 address i’d allocated.

Here’s a much nicer look at that configuration.

interface GigabitEthernet0/0
 description [Link to 3850]
 ip address 172.22.39.65 255.255.255.248

interface ucse 4/0
 description [UCS-E Series CIMC Link]
 ip unnumbered GigabitEthernet0/0
 imc ip address 172.22.39.67 255.255.255.248 default-gateway 172.22.39.65
 imc access-port shared-lom console

interface ucse4/1
 switchport mode trunk

ip route 172.22.39.67 255.255.255.255 ucse4/0
