PortAdmin - save changes in HP 5130 switch?
by Mattias Söderholm 13 Feb '17

13 Feb '17

Hi. We have now inserted some HP 5130 EI (also HP 5700) switches in NAV and want to use PortAdmin. Everything works except saving to memory. The problem is the save command! For HP Procurve switches you use "save" or "write memory" commands to save changes and it's done. HP 5130 EI is a little bit different. There you must use "save force", if you only use "save" command you have to answer some questions. Can this be fixed? Regards Mattias

Netmap question
by etiennel＠cos.flag.org 12 Sep '16

Hello, Very nice piece of software - most useful network monitoring tool I have seen in the open-source world. I have a question on the Netmap tool - I'm trying to have external links show and I wasn't able to. The scenarios are: - Edge router connected to the ISP. I can't add the ISP as a netbox as I don't have SNMP query access. So I added it as a server. How can I show on Netmap the edge router, the ISP end-device with a link between the two so I can see the bandwidth utilization and status? - A similar scenario, but with VPNs. I have a VPN router with multiple Tunnel interfaces (Csico) establishing a VPN with remote offices. I don't have SNMP of the remote offices' routers. How can I show this in Netmap tool - showing my VPN router with links to remove devices. I was able to do a similar thing with computers plugged into my switches, but in this case, I guess NAV uses the MAC address to match the device (in this case environment monitoring) with the switch port. Thank you. Etienne

Weird LLDP discovery

Hello, I'm using nav in a "simple" lab environment. I have a firewall (Juniper SRX3400) acting as GW/Router between Vlans that are distributed in some rooms thanks to switches (Cisco and Juniper). In particuler I have a direct fiber link between a Cisco 4948 (named 4948-Datacenter) and a Juniper QFX3500 (named QFX3500-DC). Port of Cisco is Te1/49 and port of QFX is xe-0/0/43 On the map and on the report, I see this on Direct neighborship candidates for 4948-datacenter: Sysname Interface source Candidate neighbor Candidate neighbor port control 4948-datacenter.sdn.lab Te1/49 lldp 3750-core.sdn.lab Gi1/0/24 4948-datacenter.sdn.lab Te1/50 lldp qfx3500-dc.sdn.lab xe-0/0/43.0 I see also this for qfx3500-dc: qfx3500-dc.sdn.lab xe-0/0/43.0 lldp 4948-datacenter.sdn.lab Te1/49 and this: 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/45 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/46 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/47 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/48 3750-core.sdn.lab Gi1/0/25 lldp 3750-ucs.sdn.lab Gi1/0/25 On the devices, I have not that (see end of messages). I suspect a mis interpretation of snmp get on the 4948 but cannot be sure :/ I've put everything in a file in case it's hard to see on the mail. How can we proceed to have the correct information?

NAV with Cisco 3850
by Mischa Diehm 25 Jul '16

25 Jul '16

Hi, we have a 3850 Stack with 3x ES-C3850-48T-S and 5x WS-C3850-12X48U. When we try to PortAdmin and edit a Port we get (see also attached Jpg): „IP device found but has no type“ Any ideas?

NAV and API exports
by Mischa Diehm 22 Jul '16

22 Jul '16

Hi, We are programming an inventory tool that uses NAV as one of its main datasources. We are now trying to get the Serial (lots of cisco here) for a given device. In the ipdevinfo overview we see the serial (for stacks there are even the stackmembers with serials listed). My questions is if we there is a way to get this information through the API and if yes how we could retrieve it? My second questions is if there is an easy documented way to extend the API with stuff like that or e.g. Status info like „is the box currently online“? Is there a roadmap towards what should and will be implemented regarding the exporsure through the API (maybe even write stuff?) Thanks a lot, Mischa -- Mischa Diehm | Network Team (NINS) UniBasel | IT-Services (ITS) Klingebergstr. 70 | CH-4056 Basel Tel. +41 61 267 1574 | https://its.unibas.ch
