I86bi Linuxl3-adventerprisek9-m2 157 3 | May 2018.bin

Cisco IOU/IOL binaries require an internal license key authentication file named iourc to run. Without this text file placed in the same directory as the binaries, the virtual routers will crash immediately upon booting, throwing a license validation error. Network engineers must ensure their testing environment references a valid, authorized iourc text file with appropriate host license definitions. 6. Known Limitations of IOL Images

Advanced Enterprise Services is the specific feature set included in the i86bi-linuxl3-adventerprisek9-m2.157-3.May_2018.bin i86bi linuxl3-adventerprisek9-m2 157 3 may 2018.bin

: Designed for Intel x86 architectures running a Linux backend. Cisco IOU/IOL binaries require an internal license key
