Feature Keys

The following describes common problems related to feature keys.
Problem
A file-based feature key does not match the
hardware
Section 6.2

Ethernet Ports

The following describes common problems related to Ethernet ports.
Problem
A link seems fine when traffic levels are low,
but fails as traffic rates increase OR a link
can be pinged but has problems with FTP/
SQL/HTTP/etc.
Feature Keys
Solution
Each file-based feature key is licensed to a particular device. When transfering a feature
key from one device to another, such as when configuring a backup unit to replace a
malfunctioning device, the device will detect a hardware mismatch with the key and trigger
an alarm.
Do not transfer file-based feature keys between devices. Contact a Siemens Canada Ltd.
sales representative to order a feature key matching the serial numbers of the hardware in
the destination device.
Solution
A possible cause of intermittent operation is that of a 'duplex mismatch'. If one end of the
link is fixed to full-duplex and the peer auto-negotiates, the auto-negotiating end falls back to
half-duplex operation.
At lower traffic volumes, the link may display few if any errors. As the traffic volume
rises, the fixed negotiation side will begin to experience dropped packets while the auto-
negotiating side will experience collisions. Ultimately, as traffic loads approach 100%, the
link will become entirely unusable.
The ping command with flood options is a useful tool for testing commissioned links. The
command ping 192.168.0.1 500 2 can be used to issue 500 pings each separated by
