Unable to discover some new switches

  • 1.  Unable to discover some new switches

    Posted 04-26-2017 08:03 AM

    Good day to everyone!

    I am a fresh networking guy. My employer has tasked me with setting up BNA from an old IronView installation they used to run but it stopped years ago. So I was able to get BNA 14.0.1 installed and it discovered everything just fine. However, I have added 4 switches (FCX648S) since then and only one of them has been discovered. I tried discovering them by IP but no go. All 4 switches were configured using standard template for configuration so they all have the same settings. Can anyone take a guess as to why 1 of them would be discovered by not the other 3?

     

    Thanks!

    Good morning,

     

    device type FCX648S is supported by BNA 14.0.1 which is good, the minimum firmware level should be 06.0.00, so can you please check if the switches are on 06.0.00 or above.

    The most common reason in this case is an IP/firewall issue: Can you access all four switches from your BNA server via port 80/443? If you use SSL, try port 443, if not try port 80. I'm not familiar with FastIron switches but maybe you have activated an IPfilter/IPtables which prevents BNA from discovery of the affected switches.

    All the switches are running:

    I assume snmp-client  on FCX is not configured, for this reason you cannot discover the switch trough BNA

     

    login to the switch trough a CLI

     

    1) telnet@TH24_ICX6430>enable

    2) telnet@TH24_ICX6430#conf term
         telnet@TH24_ICX6430(config)#

     

    3) telnet@TH24_ICX6430(config)#snmp-client
      A.B.C.D   IP address
      ipv6      IPv6 address
    4) telnet@TH24_ICX6430(config)#snmp-client "set the PC/Server IP address where BNA is installed"

     

    5) telnet@TH24_ICX6430(config)#write mem

     

    to save the config.

     

    now you should be able to discovery the switch.

    Thanks for your suggestion, I updated the SNMP Client as you suggested but it made no difference. Below is the SNMP configurations for the one that is working:

     

    snmp-server host A.B.C.230 version v3 xxxxxxxx
    snmp-server host A.B.C.62 version v3 xxxxxxxx
    snmp-server group admingroup v3 priv read all write all notify all
    snmp-server user xxxxxxxx

     

    This a non-working one after your suggested changes:

     

    snmp-server host A.B.C.230 version v3 xxxxxxxx
    snmp-server host A.B.C.62 version v3 xxxxxxxx
    snmp-server group admingroup v3 priv read all write all notify all
    snmp-server user xxxxxxxx
    snmp-client A.B.C.62

     

    .62 is the BNA server. BNA returns an "x.x.x.x did not respond to SNMP". These IPs were recycled from old switches in the same place, I'm not sure if that matters. The old switches are no longer showing in BNA.

    On the non-working one, I did configure the SNMP Client as per your instructions. The SNMP server settings were already configured and are configured the same on all the switches.

    I'll try to find old config guide for FW 07.0.xx , however I think this is the same as 07.4.xx and above

     

    additional, accord the BNA Release Notes ( i see you want to use BNA 14.0.1 ) at least FW 07.1.x is required !!!!
