Chapter 7 Functional Restrictions

This section provides information on all of the functional restrictions of the Release 4.0.1 switch software. The functional restrictions are documented alphabetically by functional area (for example, VLANs, DVMRP, IP).

Hardware

Gigabit Ports Do Not Perform Auto-negotiation

Cajun Gigabit Ethernet ports operate at 1 Gbps, full duplex and have been widely tested for interoperability with other devices. Currently, these ports do not support auto-negotiation. If you connect a Cajun gigabit port to a device that supports auto-negotiation, you must disable auto- negotiation on the non-Cajun device to ensure proper operation.

Hot Swapping Modules

If your switch supports a large configuration file, such as the startup.txt file, inserting and configuring a new module while the switch is operational may cause console and telnet CLI sessions to pause momentarily.

Link Status

When a large number of VLANs or endstations are on a hunt group, it may take several seconds for the link status LED to change upon failure.

Ping

Unable to Ping the Inband Interface on a Layer 2 device. This problem does not occur with Layer 3 devices or with the Out of Band Interface.
