ignore df enable \[command] frag ignore df enable \[purpose] configure to ignore the don't fragment (df) flag within the map domain \[view] map domain view \[notes] this is used when a packet with the df bit set to 1 needs to be fragmented normally after passing through the device \[use cases] sonic# configure terminal sonic(config)# map e domain test1 br sonic(config map e domain test1)# frag
