switch command

List management

[{iface | mac | numrange | match}]

Parameters "add" and "del" are used to add or delete values to the specified list (except "match").

• "VALUE" – one or several values to be added or deleted from the list.

dump [name] [WILDCARD]

Displays the list content.

• "name" – list name.
• "WILDCARD" – search filter.

rename NEWNAME

Renames the list.

• "NEWNAME" – new list name.

file FILENAME

[flush|remove]

• "flush" – clears the list content.
• "remove" – deletes the list from the switch configuration.

Switch Group Management

{add | del} IFNAME[:{TAG|0}] ...

Adds or deletes specified interfaces to/from the switch group:

• "add|del" – adds/deletes specified interfaces to/from the switch group. If "add" parameter is used and there is no switch group with ID identifier, it will be automatically created.
• "IFNAME" –  network interface name which should be added or deleted from the switch group.
• "TAG" – allows different manipulations with VLAN tags of the packet when the packet is sent through this interface. The following options are available:
  • "TAG" is specified for the interfaces and its value is >0. That means that any packet forwarded to the interface by the switch will be tagged with a VLAN tag "TAG". If the packet already had a tag, this tag will be retagged to "TAG".
  • "TAG" is not specified. This means that the packet stays unmodified.
  • "TAG" is specified and its value is zero. This means that the packet sent through this interface will be untagged if it was previously tagged or sent without any changes if it was not tagged.

Enables/disables switching mode. The following modes are available in WANFleX:

• "repeater" – group switches the packets simply by sending them to all the device’s interfaces except the one the packet was received from.
• "trunk" – the group switches all the packets received through "eth*" interfaces in such a way that when packets are sent to "rf*" interfaces, these packets are places in a group with a number corresponding to the packet’s VLAN TAG. When receiving the packet from "rf*" interfaces, trunk group sends these packets to "eth*" interface tagging them with a switch group number this packet was received from.
• "uncoupled" – if a ring/redundant network is connected to a core network in multiple points, STP loops can be formed in the core network. Thus, STP enabled switches may block some of the links and leed to inefficient network loading. Switch groups with "uncoupled" parameter blocks the traffic between each other even if they have the same switch group number. This does not affect the traffic to come into the wireless network. For the incoming traffic intermediate nodes only use the closest uncoupled node. This improves the effectiveness of network utilization.

in-trunk [{ID|0}]

nvlan {[on]|off}

info INFO_STRING

setid NEWID

Changes switch group ID.

dump [interface] [WILDCARD]]

Displays the database of all known MAC addresses.

• "interface" – displays the database of all known MAC addresses by grouping them according to interfaces.
• "WILDCARD" – the output will be filtered according to the selected criteria.

• "showrules" – displays detailed information about the group’s classification rules, including the hits counter for each rule.
• "showblack" – displays the list of MAC addresses that are blocked due to the indeterminacy of their owner.

stp { off | on | dump }

stp priority [PRIO]

Sets STP priority of a switch.

• "PRIO" – priority value. If priority is not specified then default value (57344) is set. When setting priority value it will be automatically rounded down to a value divisible by 4096.

stp forwarddelay [DELAY]

Sets STP "forward delay" parameter, which determines a time that switch spend in "listening" and "learning" states.

• "DELAY" – time value in seconds. If not specified default value is 15 seconds.

stp maxage [TIME]

Sets STP "MAX age" parameter, which determines time for switch to deliver BPDU-packet.

• "TIME" – value in seconds. If not specified default value is 20 seconds.

stp port IFNAME priority [PRIO]

Sets the switch port STP priority.

• "IFNAME" – interface name.
• "PRIO" – port priority value. If not specified default value is 128. When setting priority value it will be automatically rounded down to a value divisible by 16.

stp port IFNAME cost [COST]

stp [vlan TAG]

Sets VLAN tag for STP in selected switch group.

igmp { off | on }

Enables/disables the "IGMP-snooping" function for the switch group.

setpri|addpri PRIO

Allows to set/increase the priority of packets passing through the group.

• "setpri" – changes a priority to the value specified in the command. When using "-1" value a package priority is dropped to the lowest priority.
• "addpri" – changes a priority only in case it is higher than the previous one (the smaller is the value the higher is the priority). So you can only increase priority using "addpri" parameter.

qmch CHAN

{deny | permit}

Permits/denies processing and sending out the packets which belong to this group.

igmp dump [detail] [name]

igmp lmqt Value

igmp gmi Value

igmp static-add MCAST IF_NAME [MAC]

igmp static-del MCAST IF_NAME [MAC]

igmp router-port { off | on }

igmp flood-reports { off | on }

igmp srcip IP

igmp zero-query-permit { off | on }

igmp querier [vlan N] {start|stop|clear}

Enables/disables the "Querier" function, which substitutes the functions of Multicast Router in video systems with "IGMP Snooping" using.

• "vlan N" – enables multicast packets transmittion with using VLAN.
• "clear" – deletes "IGMP Querier" configuration.

igmp querier [[no]election] [source IP] [mcast X[,Y,...]]

• "[no]election" – when the IGMP Querier function is enabled, disables/enables the process of election of the IGMP Querier operating on the network segment. According to the standards, each network segment should have a single IGMP Querier, that has the lowest source IP address. By default is enabled.
• "source X" – sets source IP address for Multicast packets.
•  "mcast X[,Y,...]" – sets concrete Multicast Group (or a number of groups) to be allowed for subscription.

igmp querier interval Value

Limits the number of active unique IGMP multicast group. Once the group limit is reached, subsequent join requests are rejected.

• "IF_NAME" – network interface to make limitation.
• "include $ACL" – list of addresses/networks covered by this limitation.
• "except $ACL" – list of exceptions.

flood-unicast { off | on }

Enables/disables "flood-unicast" mode, allowing to send unicast packets as broadcast, sending them through all interfaces included in the switch group.

inband { off | on }

order N

Sets the DHCP relay identifier format in Option 82.

• "mac" – MAC address by default.
• "ASCII-string" – ASCII encoded identifier.
• "HEX-string" – HEX encoded identifier.
  

dhcp-snooping option-82 untrusted-policy { drop | keep | replace }

Interface management

interface IFNAME mac-limit N

Switching rules management

remove

src, dst, vlan, iface, proto, match LIST

deny | permit

Sets the decision for the corresponding rule.

Sets/increases the priority of packets passing through the group.

• "setpri" – changes a priority to the value specified in the command. When using "-1" value a package priority is dropped to the lowest priority.
• "addpri" – changes a priority only in case it is higher than the previous one (the smaller is the value the higher is the priority). So you can only increase priority using "addpri" parameter.

Management commands

resynchronize

trace { off | on | verbose | filter "pcap expr"}

stptrace { off | on }

stpblock { off | on }

• "on" – prevents STP frames forwarding in the switch mode when STP support is disabled.
• "off" – allows STP frames forwarding.

Enables/disables the STP MINT mode.

STP MINT mode is used to exclude the wired switches with the enabled STP protocol influence on the network operation. The mode blocks the BPDU frames of the STP protocol configured on wired switches so that the switch cannot detect the loop and block its ports. STP MINT mode in conjunction with the RSTP protocol enabled in the Infinet devices allows to break the loop and support the PRF protocol functioning that operates through the wired segment.

dead-interval <DEAD_INTERVAL_IN_SECONDS>

{start | stop | restart}

Starts/stops/restarts the switch.

{destroy}

Clears the switch configuration.

statistics [(clear|help|ID)]

Displays switch statistic. Shows the information on forwarded/flooded/dropped packets and records of the switch MAC address table (DB Records). Unicast, broadcast and flood packets statistic is made separately.

• "clear" – clears the switch statistic.
• "help" – shows a list of the drooped packets reasons descriptions used in the switch statistics command output.
• "ID" – switch group ID. If specified the output displays separate packet stats for each VLAN that belongs to that switch group.

Displays IGMP hosts list, which are subscribed to a multicast group from all groups.

• "detail" – shows detailed information about subscribers.
• "name" – shows the information for a specific gateway.

maxsources (MAXSOURCES|0)

Sets the maximum allowed number of records in the switch MAC address table. The default number of records is 5000. If "0" value is used the number of records is set to minimum possible (500).
