Restrictions

The following restrictions apply to Cisco Catalyst 6509 switches that are installed in a multishelf system:

•Both Catalyst switches must operate with the same Cisco IOS software release.

•The spanning tree implementation of Cisco CRS-1 control Ethernet assumes that all Catalyst switch ports connected to the multishelf system are kept in VLAN 1.

•The Gigabit Interface Converter (GBIC) transceiver module used on the Catalyst switches must match the SFP optic used on each RP and SCGE card in the system. The GBIC can be either LX/LH or SX, but the same type must be used on both ends.

Note Both Catalyst switches must be dedicated for use with the multishelf system. The Catalyst switches should not be used for any other purpose.

Before You Begin

Before you begin to bring up the Catalyst 6509 switches, consider the following:

•The Catalyst switches must be installed, including all cables properly connected between the switches and the Cisco CRS-1 router.
