In pcap-filter.manmisc.in, we have some keywords with optional argument as:
vlan [vlan_id]
mpls [label_num]
pppoes [session_id]
geneve [vni]
vxlan [vni]
If we choose <argument>, we will have:
vlan [<vlan_id>]
mpls [<label_num>]
pppoes [<session_id>]
geneve [<vni>]
vxlan [<vni>]
If we choose ARGUMENT, we will have:
vlan [VLAN_ID]
mpls [LABEL_NUM]
pppoes [SESSION_ID]
geneve [VNI]
vxlan [VNI]
The latter is easier to read, in my opinion, with fewer characters.
