Aruba switches Dante AV setup

  • 1.  Aruba switches Dante AV setup

    Posted Nov 10, 2022 06:15 AM
    Hello there,

    We have the below Aruba switches on campus: 
    Product Name : R0X25A 6410 Chassis
    ArubaOS-CX Version : FL.10.07.0030

    I have to setup Dante AV on capability on Aruba switches. Here are some of the requirments:
    - Enable IGMP snooping (this has to be enabled under layer-2 vlan)
    - Enable IGMP snooping Querier on one switch  (I think this has to be done under SVI)
    - Enable IGMP immediate/fast leave on  switches (I think this has to be done under SVI)
    - Disable Energy Efficient Ethernet on switches (how it is done?)

    I would appreciate if anyone can guide me on the configuration

    Hello faadi,

    Following is an IGMP setup example p.22 :
    https://www.arubanetworks.com/techdocs/AOS-CX/10.07/PDF/5200-7876.pdf
    ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    IGMP configuration example
    The output of the following show running-config command shows an example of an IGMP configuration
    with IGMP snooping.
    On the 6400 Switch Series, interface identification differs.
    switch# show running-config
    Current configuration:
    !
    !
    !
    !
    !
    vlan 1
    no shutdown
    vlan 2
    ip igmp snooping enable
    ip igmp snooping version 2
    ip igmp snooping forward 1/1/1
    ip igmp snooping blocked 1/1/3
    ip igmp snooping static group 239.1.1.10
    ip igmp snooping static group 239.1.1.11
    interface 1/1/1
    no shutdown
    no routing
    vlan access 2
    interface 1/1/2
    no shutdown
    no routing
    vlan access 2
    interface 1/1/3
    no shutdown
    no routing
    vlan access 2
    interface vlan2
    no shutdown
    ip address 20.1.1.1/24
    ip igmp enable
    ip igmp version 2
    ip igmp querier interval 5
    ip igmp robustness 5
    ip igmp last-member-query-interval 2
    ip igmp query-max-response-time 50
    ip igmp static-group 239.1.1.1
    ++++++++++++++++++++++++++++++++++++++++++

    In regards to the IGMP snooping it starts at p.47 of the same guide.

    In regards to the Energy Efficient Ethernet:
    switch(config)# interface 1/1/1 
    switch(config-if)#     no energy-efficient-ethernet

    Hope this helps!

    Thank you for the response, Alex. I hav a few questions. 

    -Is the igmp forwarding, blocked and static groupcommand optional or required?
    - Is the igmp querier interval command used to enable igmp querier? 
    - The 'no energy-efficient-ethernet' command is not available on the 6400 switches. What is the alternate or default?

    Hello faadi,

    The commands igmp forwarding, blocked and static groupcommand  are optional this is just an example from the guide you may not need them.
    These commands are descibed in the guide I put in my answer before.
    IGMP querier command is the following:
    +++++++++++++++++++++++++++++++++++++++++++++++++++
    ip igmp querier

    Syntax
    ip igmp querier
    no ip igmp querier

    Description
    Configures an IGMP querier on an interface, depending on the command context you are in. This functionality will allow an interface to join in the querier-election process.
    The no form of this command disables IGMP querier on an interface.

    Command context
    config-if-vlan
    config-if
    config-lag-if

    Authority
    Administrators or local user group members with execution rights for this command.

    Examples
    Configuring an IGMP querier on interface VLAN 2:

    switch(config)# interface vlan 2
    switch(config-if-vlan)# ip igmp querier
    switch(config-if-vlan)# no ip igmp querier
    ++++++++++++++++++++++++++++++++++++++++++++++++

    In regards tot he energy efficient ethernet the command is available in 6400 switches as mentioned in the 6400 CLI guide:
    https://www.arubanetworks.com/techdocs/AOS-CX/10.10/HTML/cli_6300-6400/Content/Chp_IfaceCfg/Iface_cmds/ene-eff-eth-10.htm

    You may check if you have energy efficient ethernet on your ports on your device.
    Also you may check it's status with the following command:

    show interface energy-efficient ethernet

    Hope this helps!

    hi ,
    Thanks for your answer. I am having issue configuring fastleave on switches. The error message is strange and I cannot find any informaiton on this error message. I have tried it on multiple switches and interfaces but this command is not accepted. 

    Aruba-SW(config-if)# ip igmp snooping fastleave vlan 54
    Interface 1/5/9 on which IGMP configuration is attempted does not exist.

    Hello faadi,

    This command is used under vlan context:

    ip igmp snooping fastleave

    Syntax

    ip igmp snooping fastleave <PORT-LIST>

no ip igmp snooping fastleave <PORT-LIST>

    Description

    Enables the switch to immediately remove the IGMP client from its IGMP table and cease transmitting multicast traffic to the client.

    The no form of this command disables fastleave on the specified ports.

    Command context

    config-vlan

    Parameters

    fastleave <PORT-LIST>

    Specifies a list of one or more ports to be configured as fastleave ports. You can specify a single port, a comma-separated list of ports or a range of ports such as 1/1/1-1/1/3.

    Authority

    Administrators or local user group members with execution rights for this command.

    Usage

    IGMP fastleave is configured for ports on a per-VLAN basis. Upon receiving a Leave Group message, the querier sends an IGMP Group-Specific Query message out of the interface to ensure that no other receivers are connected to the interface. If receivers are directly attached to the switch, it is inefficient to send the membership query as the receiver wanting to leave is the only connected host.

    When a fastleave enabled switch port is connected to a single host and receives a leave, the switch does not wait for the querier status update interval, but instead immediately removes the IGMP client from its IGMP table and ceases transmitting multicast traffic to the client. (If the switch detects multiple end nodes on the port, Fastleave does not activate regardless of whether one or more of these end nodes are IGMP clients.) This processing speeds up the overall leave process and also eliminates the CPU overhead of having to generate an IGMP Group-Specific Query message.

    Examples

    Configuring fastleave ports for the VLAN:

    switch(config)#
    vlan 2 
    switch(config-vlan)#
    ip igmp snooping fastleave 1/1/1 
    switch(config-vlan)#
    ip igmp snooping fastleave 1/1/1-1/1/2 
    switch(config-vlan)#
    ip igmp snooping fastleave 1/1/1,1/1/2-1/1/3 
    switch(config-vlan)#
    no ip igmp snooping fastleave 1/1/1 
    switch(config-vlan)#
    no ip igmp snooping fastleave 1/1/1-1/1/2

    Hope this helps!
