CE-100T-8 Pool Allocation Example
This information can be useful in freeing up the bandwidth required for provisioning a circuit if there is
not enough existing capacity in any one pool for provisioning the desired circuit. The user can look at
the distribution of the existing circuits among the four pools and decide which circuits to delete in order
to free space for the desired circuit.
For example if a user needs to provision an STS-3c or STS-1-3v on the SONET CE-100T-8 card shown
in
Figure 24-5 , an STS-3c or STS-1-3v worth of bandwidth is not available from any of the four pools.
The user needs to delete circuits from the same pool to free bandwidth. If the bandwidth is available but
scattered among the pools, the circuit cannot be provisioned. Looking at the POS Port Map table, the
user can determine which circuits belong to which pools. The Pool and Port columns in
Figure 24-5 show
that Port 6 and Port 7 are both drawn from Pool 1, and that no other circuits are drawn from Pool 1.
Deleting these two STS-1 circuits will free an STS-3c or STS-1-3v worth of bandwidth from a single
pool.
If the user did not determine what circuits to delete from the table information, he might delete the STS-1
circuits on Port 3, Port 5 and Port 6. This frees an STS-3c or STS-1-3v worth of bandwidth, but the
required bandwidth is not available from a single pool and the STS-3c or STS-1-3v circuit is not
provisionable.
Both Port 6 and Port 7
belong to Pool 1
