  • Page 60: Creating Stacking Trunks On The Icx 7450

    The ICX 7450 supports two stacking trunks per stack unit when the 4X10GF module in slot 2 is used for stacking. You can configure one or two stacking trunks on an ICX 7450 stand-alone after changing default stacking ports to 1/2/1 and 1/2/3 as shown in the following example.

However, if there is a static trunk configuration associated with the unit, the active controller cannot remove the dynamic configuration. In this case, you must remove the static trunk and use the no stack unit stack-unit command to manually remove the configuration.
