IBM ON DEMAND
Cloud connectivity guide: On Demand
IBM DIRECT LINK
To create a new IBM Direct Link Connect service, customers need to create a Direct Link Connect service via the IBM portal and select the location (e.g. Amsterdam), provider (Colt) and a bandwidth between 50Mbps and 5Gbps. Customers will also be required to select routing details.
Once the service has been created, IBM need to approve the request – this may take several hours.
All Direct Link services are handed over on a shared NNI between Colt and IBM.
CONNECTIONS TO IBM DIRECT LINK CONNECT PORTS
Connections to IBM Direct Link Connect ports are based on a 1:1 circuit connection to hosted port mapping. The cloud B end configuration is always based on single 802.1Q VLAN* – this is automatically configured when the default “Cloud VLAN” option is selected. &#xNAN;The Ethertype is 8100, although this is not visible to customers
The standard VLAN modes apply at the customer A end port, which are summarised in the table below:
Open port
Circuit occupies whole A end port
Port based handover, all traffic on the customer port is mapped to the cloud port
Add VLAN
Customer uses single tagged VLAN to map traffic
VLAN added on egress, towards customer (in translation mode). VLAN can be S-VLAN (88a8) or C-VLAN (8100). Standard H&S config. VLAN contains three “inner” VLANs. Customer needs to map inner VLANs to “outer” tag
IBM DIRECT LINK CONNECT CONFIGURATION
The below diagram summarises the configuration:
END-TO-END CUSTOMER JOURNEY
The customer journey to establish end to end connectivity to an IBM interconnect port is illustrated below:
IBM DIRECT LINK DEDICATED PORTS
Connections to 10Gbps IBM Direct Link dedicated ports can be supported via a standard DCNet On Demand port – providing a DC cross connect is requested via the On Demand portal (the IBM LOA should be attached to the cross connect request).
