As described in “Configuring 802.3ad Link Aggregation” on page 13, the P-7500 system supports the concept of a LAG which bundles multiple physical interfaces together to form a single virtual interface. A single LAG is supported on the P-7500 system, which may contain any combination of physical NAB ethernet ports. To applications, the LAG appears as a single IP interface, but inside the LAG, packets are transmitted and received on the bundled physical ports.
By default through the setup Privileged EXEC command, the physical interfaces on the NAB are all configured as ’lag1’ upon completing the initial software configuration procedure described in
TIBCO Messaging Appliance P-7500 Getting Started. Thus, it is common to see only a single IP address associated with P-7500 NAB interface through lag1.
