* Parse subinterface names.
*
* The following subinterface syntax is supported. The first two are for
* backwards compatability:
*
* <intf-name> <id>
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a single dot1q vlan with vlan id <id> and exact-match semantics.
*
* <intf-name> <min_id>-<max_id>
* - a set of the above subinterfaces, repeating for each id
* in the range <min_id> to <max_id>
*
* In the following, exact-match semantics (i.e. the number of vlan tags on the
* packet must match the number of tags in the configuration) are used only if
* the keyword exact-match is present. Non-exact match is the default.
*
* <intf-name> <id> dot1q <outer_id> [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a single dot1q vlan with vlan id <outer_id>.
*
* <intf-name> <id> dot1q any [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a single dot1q vlan with any vlan id.
*
* <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
* <inner_id>.
*
* <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
*
* <intf-name> <id> dot1q any inner-dot1q any [exact-match]
*
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1q vlan with any outer vlan id and any inner vlan id.
*
* For each of the above CLI, there is a duplicate that uses the keyword
* "dot1ad" in place of the first "dot1q". These interfaces use ethertype
* 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
* tagged packets the inner ethertype is always 0x8100. Also note that
* the dot1q and dot1ad naming spaces are independent, so it is legal to
* have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
*
* <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
* - a subinterface with the name <intf-name>.<id>. The subinterface
* is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
* id <inner_id>.
*
* <intf-name> <id> untagged
* - a subinterface with the name <intf-name>.<id>. The subinterface
* has no vlan tags. Only one can be specified per interface.
*
* <intf-name> <id> default
* - a subinterface with the name <intf-name>.<id>. This is associated
* with a packet that did not match any other configured subinterface
* on this interface. Only one can be specified per interface.

/*?
* This command is used to add VLAN IDs to interfaces, also known as subinterfaces.
* The primary input to this command is the '<em>interface</em>' and '<em>subId</em>'
* (subinterface Id) parameters. If no additional VLAN ID is provide, the VLAN ID is
* assumed to be the '<em>subId</em>'. The VLAN ID and '<em>subId</em>' can be different,
* but this is not recommended.
*
* This command has several variations:
* - <b>create sub-interfaces <interface> <subId></b> - Create a subinterface to
* process packets with a given 802.1q VLAN ID (same value as the '<em>subId</em>').
*
* - <b>create sub-interfaces <interface> <subId> default</b> - Adding the
* '<em>default</em>' parameter indicates that packets with VLAN IDs that do not
* match any other subinterfaces should be sent to this subinterface.
*
* - <b>create sub-interfaces <interface> <subId> untagged</b> - Adding the
* '<em>untagged</em>' parameter indicates that packets no VLAN IDs should be sent
* to this subinterface.
*
* - <b>create sub-interfaces <interface> <subId>-<subId></b> - Create a range of
* subinterfaces to handle a range of VLAN IDs.
*
* - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any [exact-match]</b> -
* Use this command to specify the outer VLAN ID, to either be explicit or to make the
* VLAN ID different from the '<em>subId</em>'.
*
* - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any inner-dot1q
* <vlanId>|any [exact-match]</b> - Use this command to specify the outer VLAN ID and
* the inner VLAN ID.
*
* When '<em>dot1q</em>' or '<em>dot1ad</em>' is explicitly entered, subinterfaces
* can be configured as either exact-match or non-exact match. Non-exact match is the CLI
* default. If '<em>exact-match</em>' is specified, packets must have the same number of
* VLAN tags as the configuration. For non-exact-match, packets must at least that number
* of tags. L3 (routed) interfaces must be configured as exact-match. L2 interfaces are
* typically configured as non-exact-match. If '<em>dot1q</em>' or '<em>dot1ad</em>' is NOT
* entered, then the default behavior is exact-match.
*
* Use the '<em>show interface</em>' command to display all subinterfaces.
*
* @cliexpar
* @parblock
* Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11}
*
* The previous example is shorthand and is equivalent to:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match}
*
*
* Example of how to create a subinterface number that is different from the VLAN ID:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100}
*
*
* Examples of how to create q-in-q and q-in-any subinterfaces:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200}
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any}
*
* Examples of how to create dot1ad interfaces:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11}
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200}
*
*
* Examples of '<em>exact-match</em>' versus non-exact match. A packet with
* outer VLAN 100 and inner VLAN 200 would match this interface, because the default
* is non-exact match:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100}
*
* However, the same packet would NOT match this interface because '<em>exact-match</em>'
* is specified and only one VLAN is configured, but packet contains two VLANs:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match}
*
*
* Example of how to created a subinterface to process untagged packets:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 untagged}
*
* Example of how to created a subinterface to process any packet with a VLAN ID that
* does not match any other subinterface:
* @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 7 default}
*
* When subinterfaces are created, they are in the down state. Example of how to
* enable a newly created subinterface:
* @cliexcmd{set interface GigabitEthernet2/0/0.7 up}

/*?
* This command is used to start or stop a packet capture, or show
* the status of packet capture.
*
* This command has the following optional parameters:
*
*
* - <b>rx</b> - Capture received packets
*
* - <b>tx</b> - Capture transmitted packets
*
* - <b>drop</b> - Capture dropped packets
*
* - <b>off</b> - Stop capturing packets, write results to the specified file
*
* - <b>max <nn></b> - Depth of local buffer. Once '<em>nn</em>' number
* of packets have been received, buffer is flushed to file. Once another
* '<em>nn</em>' number of packets have been received, buffer is flushed
* to file, overwriting previous write. If not entered, value defaults
* to 100. Can only be updated if packet capture is off.
*
* - <b>max-bytes-per-pkt <nnnn></b> - Maximum number of bytes to capture
* for each packet. Must be >= 32, <= 9000.
*
* - <b>preallocate-data</b> - Preallocate the data buffer, to avoid
* vector expansion delays during pcap capture
*
* - <b>free-data</b> - Free the data buffer. Ordinarily it's a feature
* to retain the data buffer so this option is seldom used.
*
* - <b>intfc <interface-name>|any</b> - Used to specify a given interface,
* or use '<em>any</em>' to run packet capture on all interfaces.
* '<em>any</em>' is the default if not provided. Settings from a previous
* packet capture are preserved, so '<em>any</em>' can be used to reset
* the interface setting.
*
* - <b>filter</b> - Use the pcap trace rx / tx / drop filter, which
* must be configured. Use <b>classify filter pcap...</b> to configure the
* filter. The filter will only be executed if the per-interface or
* any-interface tests fail.
*
* - <b>error <node>.<error></b> - filter packets based on a specific error.
* For example: error {ip4-udp-lookup}.{no_listener}
*
* - <b>file <name></b> - Used to specify the output filename. The file will
* be placed in the '<em>/tmp</em>' directory, so only the filename is
* supported. Directory should not be entered. If file already exists, file
* will be overwritten. If no filename is provided, the file will be
* named "/tmp/rx.pcap", "/tmp/tx.pcap", "/tmp/rxandtx.pcap", etc.
* Can only be updated if packet capture is off.
*
* - <b>status</b> - Displays the current status and configured attributes
* associated with a packet capture. If packet capture is in progress,
* '<em>status</em>' also will return the number of packets currently in
* the local buffer. All additional attributes entered on command line
* with '<em>status</em>' will be ignored and not applied.
*
* @cliexpar
* Example of how to display the status of a tx packet capture when off:
* @cliexstart{pcap trace status}
* max is 100, for any interface to file /tmp/vpe.pcap
* pcap tx capture is off...
* @cliexend
* Example of how to start a tx packet capture:
* @cliexstart{pcap trace tx max 35 intfc GigabitEthernet0/8/0 file
* vppTest.pcap}
* @cliexend
* Example of how to display the status of a tx packet capture in progress:
* @cliexstart{pcap trace status}
* max is 35, for interface GigabitEthernet0/8/0 to file /tmp/vppTest.pcap
* pcap tx capture is on: 20 of 35 pkts...
* @cliexend
* Example of how to stop a tx packet capture:
* @cliexstart{pcap trace off}
* captured 21 pkts...
* saved to /tmp/vppTest.pcap...
* @cliexend
