For each chassis in a subtended network configuration to have fair access to the shared network trunk,
the chassis must have a unique ID number. The subtending host chassis places this ID number in the GFC
field of the ATM header of each cell; this ID number is then used to forward cells up the tree to the
network trunk.
You can subtend Cisco 6260 chassis with DS3/2DS3 NI-2 cards in a continuous daisy chain. However,
Note
a daisy-chained subtending scheme is not optimal for data throughput for Cisco 6260 chassis that use
DS3/2DS3 NI-2 cards.
Cisco IOS software does not manage the primary Cisco 6260 chassis and all subtended Cisco 6260
chassis as a single large Cisco 6260 system. Each Cisco 6260 chassis supports an independent Cisco IOS
processor and MIBs.
