Router
What is it?
A router is a piece of core network technology that connects the school networks that provide staff and students with network services. These include services internal to the network and to the internet. The core services include but are not limited to -
Internet
SIP
Internal sites
WAN (Wide Area Network)
LAN (Local Area Network)
The router provides many services, though not limited to the above however it is a vital piece of technology enabler to the school.
How does CSPD use it?
If you are inside of the network and browsing services whether it is an internal site or a internet based site, you are using the router. Also, if you pick up a phone/handset connected to the network you are using the router as the network traffic traverses the router to exit via the SIP endpoint to make calls.
Additional Information:
At times things go wrong, whether there are power issues or fibre cable cuts or even hardware failures, these are not limited in what could go wrong. The most common that could happen to the school are:
Power outage to the router or core cabinet
Network down, can't browse the internet/internal site
The easiest and most efficient way to resolve this is to log a ticket with Service desk. As the very first step, we would need photos of the cabinet where the router is, this is called the core cabinet. Please get these photos and attach them to the ticket when getting created. Let your TSO know that the site is down and to notify Service desk so that it gets passed on. Once it gets to First level support, a ticket will ether be created with our network support vendors or with the Service provider of the WAN network.
Common troubleshooting
Use of ping via command line
Ping the servers locally
Ping a website on the internet
Use of traceroute via command line
Traceroute to a local server/service
Traceroute to a website to the internet
If the ping to the local server responds then connectivity within the network works, if the ping to the internet does not, there could be a disruption to the connectivity which is causing the outage/loss of service. If ping to any service doesn't work, there is a disruption to a service where the ping is initiated from (ie AP's / switches that your device is connecting from is having problems.)
The traceroute commands are there to assist in troubleshooting any locally connected issues (normally there isn't, unless there is a issue with the upstream switch/fibre local to the school).
