Syntax Parameters lacp ungroup member-independent {vlt | port-channel} port-channel vlt Force all LACP port-channel members to become switchports. Force all VLT LACP members to become switchports. Defaults Command Modes Command History Not configured. CONFIGURATION Version 9.4(0.0) Supported on the FN I/O aggregator. This command is supported in Programmable-Mux (PMUX) mode only. Usage Information LACP on the VLT ports (on a VLT switch or access device), which are members of the virtual link trunk, is not brought up until the VLT domain is recognized on the access device. On the S4810, during boot-up in a stacking configuration, the system must be able to reach the DHCP server with the boot image and configuration image. During boot-up, only untagged DHCP requests are sent to the DHCP server to receive an offer on static LAGs between switches. The DHCP server must be configured to start in BMP mode. If switches are connected using LACP port-channels like the VLT peer and Top of Rack (ToR), use the port-channel parameter on the ToR-side configuration to allow member ports of an ungrouped LACP port-channel to inherit vlan membership of that port channel to ensure untagged packets that are sent by a VLT peer device reach the DHCP server located on the ToR. To ungroup the VLT and port-channel configurations, use the no lacp ungroup member independent command on a VLT port channel, depending on whether the port channel is VLT or non-VLT.
