Running the below commands: nft add table inet dev nft add set inet dev ports_udp { type inet_service\; size 65536\; flags dynamic, timeout\; timeout 30d\; } nft add element inet dev ports_udp { 53 timeout 30d counter } nft list ruleset Output: table inet dev { set ports_udp { type inet_service size 65536 flags dynamic,timeout timeout 30d elements = { 53 expires 29d23h59m56s184ms } } } Expected Output: table inet dev { set ports_udp { type inet_service size 65536 flags dynamic,timeout timeout 30d elements = { 53 expires 29d23h59m56s184ms counter packets 0 bytes 0 } } } Am I doing something wrong?
