Backup the Configuration and IOS Code
Step 1 Insert the Cisco certified eUSB disk into the USB0 on the active SUP160 board.
Step 2 Edit the configuration follow the steps below:
Please note that on SUP250, all 10G and 100G interfaces are visible regardless of whether the related QSFP module is
inserted or not. The backhaul interface numbering scheme on SUP250 is different from SUP160, shown as below:
10GE interface100GE interface
Te4/1/2 ~ Te4/1/9Hu4/1/0 ~ Hu4/1/1SUP4
Te5/1/2 ~ Te5/1/9Hu5/1/0 ~ Hu5/1/1SUP5
Therefore, we recommend the user to copy the SUP160 configuration out to the server and edit the SUP160 configuration
manually before copy back to the SUP250.
a) Replace the card type sup-pic-8x10g with sup-pic-2x100g-8x10g on both card 4/1 and 5/1.

card 1/0 cBR-CCAP-LC-40G r-phy
card 2/0 cBR-CCAP-LC-40G
card 3/0 cBR-CCAP-LC-40G
card 4/1 sup-pic-2x100g-8x10g
card 5/1 sup-pic-2x100g-8x10g
card 6/0 cBR-CCAP-LC-40G
card 7/0 cBR-CCAP-LC-40G
card 8/0 cBR-CCAP-LC-40G r-phy
card 9/0 cBR-CCAP-LC-40G r-phy
b) Relocate the backhaul related configuration based on the numbering scheme listed in the above chart. The mappings
are Ten4/1/0 – Ten 4/1/7 (SUP160) as Ten4/1/2 – Ten4/1/9 (SUP250), Ten5/1/0 – Ten5/1/7 (SUP160) as Ten5/1/2
