This command prevents deployed modems from switching to MTCM, thus triggering USCB, when they re-register for
any reason.
2.
Enable Multiple Transmit Channel mode:
configure interface cable-mac <mac> cable mult-tx-chl-mode
3.
Enable the C4/c CMTS to create upstream bonding groups dynamically:
configure interface cable-mac <mac> cable upstream-bonding-group dynamic enable
Note: When mtcm-conditional-override is set, only CMs that have the bonding bit set in the SfRequiredAttributeMask to
the hex string in the step below will be given MTCM (USCB) consideration on the CER. The following step is necessary
before USCB can take place.
4.
(Optional) Create a static upstream bonding group:
configure interface cable-mac <mac-id> cable upstream-bonding-group <int> cable-upstream
<slot>/<port>
For example, to configure an US bonding group number 100 on cable-mac 1 with US channels 1/0, 1/1, 1/2, and 1/3,
use the following command:
configure interface cable-mac 1 cable upstream-bonding-group 100 cable-upstream 1/0 1/1 1/2 1/3
5.
Verify that the config file of this modem to be bonded includes a bonding-required attribute for at least one upstream
service flow. The config file for this modem should have the following value for the attribute mask:
SfRequiredAttributeMask = hexstr: 80.00.00.00
