sw-top

This is the root switch to the Orbit network.That also includes firewall and Internal switch ports.

Top Switch layout

• Public VLANs (VLAN 50) - 4 ports (DMZ, 2 planet lab, firewall out)
• Firewall feed - 4 ports (to ASA)
• Internal (VLAN 2) - 10 ports
• Legacy sw-top VLANs - 16 ports

Legacy sw-top ports refer to the following three categories:

1. Infrastructure - Not really visible to user - Aruba, Internal, Instrumental ect - VLANs 1-6
2. Experimental - Pertains to Grid, outdoor, Sandboxes - VLANs 7,8,11-38
3. Public - Visible from outside - VLAN 50

The legacy sw-top inludes following non-used VLANs, which are ignored for the IP8800 sw-top configs:

• VLAN 1001-1005 - Cisco associated
• 9,10 - not used for any ORBIT services
