Introduction

Virtual networks are managed by VMware vSphere Distributed Virtual Switch in order to simplify and scale the network layer. If you already have access to one or many virtual networks in our environment you certainly feel more familiar with this section, if not, you are probably going to use our public networks labeled VL-1584-VSS-PUBLIC and VL-0253-EIS-VSS-CGN, which are DHCP enabled networks and have no firewall enabled due to its nature as just being temporary.

We encourage all of our customers to have a custom network segment plumbed into our environment and that can be done first by contacting U of T Network Administration Tools and then providing the allocated segment and VLAN information to the VSS Team.

This resource provides read access to all Virtual Networks permitted in our environment. If by any chance you cannot see a network and you add it to a new Virtual Machine creation request or a NIC change request, your request will not be successfully processed. If you believe you need access to a specific network, please contact us.

The following table shows a brief description and HTTP methods allowed to interact with virtual networks.

Resource	URI	Description	GET	POST	PUT	PATCH

Resource	URI	Description
Network	/network	List permitted networks and their attributes
Network object	/network/<moref>	Obtain network detail information.
Network VMs	/network/<moref>/vm	Virtual machines using a given network
Network permission	/network/<moref>/permission	Network object resource permission list.

TK stores the Cloud API Token generated as a result of the following POST request to the /auth/request-token resource:

curl -X POST https://vss-api.eis.utoronto.ca/auth/request-token -u <username>

For example, extracting the token with the jq command:

TK=$(curl -X POST https://vss-api.eis.utoronto.ca/auth/request-token -u <username> | jq -r '.token')

List

In order to list allowed Networks you should make a GET request to the endpoint /v2/network, passing your access token. As a result, you will get a reference URI /v2/network/<moref> to get detailed information about that network, human readable name and Managed Object Reference (moref). The following examples uses HTTPie and CURL to list all networks a user have access to:

http GET "https://vss-api.eis.utoronto.ca/v2/network" "Authorization: Bearer $TK"
curl -H "Authorization: Bearer $TK" -X GET "https://vss-api.eis.utoronto.ca/v2/network"

Response Body

Paging

All requests to the /network URL are paginated. The response body includes a 'meta.pages' key with everything to navigate through the results, for instance:

Key	Description

Key	Description
first_url	Contain the URLs to navigate through results.
last_url
prev_url
next_url
page	Current page
pages	Total number of pages
per_page	Results per page. Maximum 250; Default 10.
total	Total number of results

Results per page can be set by including the parameter in the URL query, so we can get the desired number of elements per page, for example:

Filtering

Networks can be filtered by adding the filter argument to the query string in the following format:

Operators can be:

Operator	Description

Operator	Description
eq	Equals
ne	Not equal
lt	Lower than
le	Lower equal
gt	Greater than
ge	Greater equal
like	Matching pattern
in	Match value in many items separated by commas

A resource can be filtered by as many attributes the request has, for instance /networks can be filtered by description, created_on, vms, vlan_id, subnet, name, admin, moref, label, updated_on, ports, etc. Thus, the following example will filter only by name=PUBLIC

Sorting

The resource provides also attribute sorting by adding the sort parameter in the URL query string in the following format:

The following example shows how to filter by label:

List specific Network Info

Some of the attributes will have an object value. Such is the case of items in attribute vms.

Name	Type	Description

Name	Type	Description
admin	string	Network owner/administrator
description	string	Virtual Network description.
name	string	Virtual Network name.
ports	integer	Number of ports in the port group.
moref	string	Network identifier
subnet	string	Network subnet with mask
vlan_id	string	VLAN id or range
vms	integer	Number of virtual machines on the network.

The following example, requests information about a particular Network using the base resource /v2/network and appending the moref to get the URI /v2/network/dvportgroup-92:

HTTP response body would look something like:
