T-Series Traffic Director Installation, Configuration and Administration Guide 3-5
Assigning VLANs, IP Addresses, and Ports
IP Addresses for Basic Load Balancing
In basic deployment mode, the T1000 processes all Unison traffic originating from and
returning to subscribers. See Figure 3-2 for a typical arrangement

of data plane IP
addresses (management and control IP addresses are not shown).
Note: IP addresses and VLAN IDs in this document are for example purposes only.
Use appropriate values for your network deployment.
Figure 3-2 Typical IP Addresses and VLAN IDs
In this example, IP addresses are assigned as follows:
• Each application blade has two (2) IP addresses in the data plane (management and
control traffic will require additional interfaces). The OSNs in this example are
“zoned,” meaning that two instances of OSN run on each blade. Each zone has two
interfaces for redundancy. Ingress and egress traffic are each handled on separate
interfaces. Note that a typical Unison deployment may have many OSN blades — in
some cases, over 100 blades.
• The T1000 has four (4) IP addresses in the data plane.
• A second T1000 has an identical data plane IP address configuration.
• T1000 supports link local (169.254.x.x, as shown) or private (for example, 10.x.x.x)
IP addresses.
1. Figure 3-2 presents a typical Unison deployment with a single ingress/egress VLAN. Note that
the T1000 is not restricted to a single VLAN. Multiple ingress and egress VLANs may be con-
figured in accordance to the instructions in this guide, typically by copy/pasting the relevant
commands to accommodate for the extra VLANs
