Changing Link Capacities Netmap
by William Daly - Network Specialist, VUSD Technology 08 Nov '17

08 Nov '17

Hello, I have sort of a different question. Here a bit of context: We currently have 17 sites throughout our school district. All of these have a 1Gbps uplink to our main district office. However, most of these sites are throttled at 100 Mbps. Of course NAV sees these links at 1 Gbps. The issue that I have is when viewing our network topology through Netmap it shows bandwidth usage based on 1 Gbps. However, the sites run at 1/10 the actual link capacity. Is there a way to 'change' Netmap to show bandwidth usage based on a different threshold? Thank you William Daly

Multicore support IPdevpool and Django Errors
by William Daly - Network Specialist, VUSD Technology 16 Okt '17

16 Okt '17

Hello, I am currently experiencing an issue with multicore with IPdevpool being enabled and encountering many errors. Essentially when I enable multi core support, the web gui stops rendering graphs at a high frequency and things do not load. In the logs it appears it shows errors with django. As soon as multi core support is turned off everything returns to normal, however my graphs become very spotty. Thanks, Will

Prefix and VLAN problems
by William Daly - Network Specialist, VUSD Technology 13 Okt '17

13 Okt '17

Hello, I am also having issues with prefixes and the corresponding VLAN tab. Initially, I went through and entered in all of my prefixes, with corresponding VLAN's, net identifications and usage type. However, after I populated the data base with nodes, the prefixes disappear and now when I go to the VLAN tab, all that shows is the net type and VLAN. I cannot edit net identifications. When I go to edit and change the organization and description, none of the changes hold. Any ideas? Thank you William Daly
