In addition to the IP parameters the following temporary switch settings are made:
• All ports in the same VLAN
• Trunking disabled for all ports
• Admin state disabled for all ports
• Link Setup set to Autonegotiation / Autocrossover for all ports
• Portsecurity disabled for all ports
• Rapid Spanning Tree global disabled
The above settings ensure that the switch can be accessed via any port using the fixed IP address 172.23.44.111. Moreover
the IP, Link, VLAN, trunking and Portsecurity settings can be made without these settings taking immediate effect. Only after
a “Booting with Flash Configuration” the stored configurations will be enabled.
Moreover the fixed IP address can be used to check the configuration of the switch (e.g. if the switch cannot be accessed
via the expected IP address because of badly configured VLANs etc.).
Booting with Fixed IP Address
This function will enable the following temporary IP settings:
• IP-address
172.23.44.111
• Network mask 255.255.255.0
The switch can then be accessed via this temporary IP address in order to configure the required switch
parameters (e. g. the IP address).
