GX 550 VC Provisioning Guidelines
GX 550 VC Provisioning Guidelines
Base Input/Output (BIO) modules support the following number of VC connection
entries, depending on the type of module:
• BIO2 modules support a maximum of 32K connection entries per phy card (a total
of 128K per BIO).
• 256-MB BIO1 modules support a maximum of 16K (16,348) connection entries
per phy card (a total of 64K per BIO).
• BIO-C modules support a maximum of 256K connection entries per
OC-48c/STM-16c phy card.
To determine the type of BIO module you have, expand the Cards class node to see a
list of all installed cards on the switch. To view a card’s attributes, right-click on the
card instance node and select View from the pull-down menu to display the View Card
dialog box.
BIO modules can store the following number of PVC endpoints in PRAM, depending
on the type of module:
• BIO2 modules can store 64,000 PVC endpoints.
• 256-MB BIO1 modules can store 16,000 PVC endpoints.
• 128-MB BIO1 modules can store 8,000 PVC endpoints.
• BIO-C modules can store 128,000 PVC endpoints.
The remainder of the BIO VC capacity is used by SVCs and/or VCs that traverse
trunks on the BIO module.
Note – See the Switch Diagnostics User’s Guide for CBX 3500, CBX 500, GX 550,
and B-STDX 9000 for more information on accessing the View Card dialog box.
Note – Keep the following VPI/VCI assignment guidelines in mind to maximize
connection entry resource use. Failure to follow these guidelines may result in Simple
Network Management Protocol (SNMP) SET failures when provisioning PVCs.
