Q

gbic gigastack 'duplex' status report via 'sho int'

most gbic modules are for single
point2point connections.
the ‘sho int’ command will report the speed
and duplex which was negatiated.

what is reported for the ‘duplex’ status
for the gbic ‘stack’ modules, which connects the module to 2 other modules
on 2 different switches? may it be that one
of the 2 connections is half and the other is
full duplex?

A

Half-duplex mode in the switches stacking means cascading the switches one after another inline.
If you connect one module to 2 other switches, creating a star topology you can use full-duplex on each port. If you don’t, make sure that the duplex/speed configuration is correct on both sides and that the cabling is in order.

The Cisco Systems GigaStack Gigabit Interface Converter (GBIC) is a versatile, low-cost, Gigabit Ethernet stacking GBIC that offers high-speed interconnectivity between Catalyst 3550, 2950G, 3500 XL and modular Catalyst 2900 XL Switches.

The GigaStack GBIC is implemented in a standard GBIC form, which offers customers the highest level of deployment flexibility and scalability-using available Gigabit Ethernet GBIC ports for high-performance stacking today while preserving the option to migrate to standard Gigabit Ethernet uplinks tomorrow.

Cisco WS-X3500-XL Management & Protocols

Management: Full Compatibility with Cisco Switch Clustering Management Technology:
  • Users can choose to deploy GigaStack GBIC stacking while benefiting from the powerful multidevice management technology available in Cisco Switch Clustering technology. Switch Clustering technology allows customers to manage a stack of devices within a wiring closet or a broadly dispersed set of devices across a campus as a single IP entity. Switch Clustering technology uses standard TCP/IP packets to distribute and collect management information for all switches in the cluster. Switch Clustering supports a broad range of physical interconnections, including the GigaStack GBIC.
