Salve a tutti e complimenti per questo fantastico forum. Ho un problema: devo collegare uno switch Cisco 2950: la porta 1 la attacco alla presa che mi fa uscire su internet (sono in uni) con un cavo cross, nelle altre porte ci attacco i pc di una piccola rete lan interna al nostro laboratorio studenti. Fatto sta che la porta 1 rimane lampeggiante arancione e i pc non riescono a collegarsi ovviamente. Lo switch è stato abbastanza "stressato" durante un corso per cui ho fatto un factory reset come consigliato anche su http://www.liniac.upenn.edu/software/xc ... HOWTO.html.
Bene....anzi male: il problema è sempre lo stesso.
Qualcuno sa consigliarmi? Grazie!!

Disabilita il CDP.
E seconda cosa....un catalyst non è uno switch normale...se sei un ambiente che usa VLAN e Trunk ovvio che nn lo puoi attaccare così come ti pare a te...ma va configurato in modo apportuno.

Nota integrativa :
Error Message
%SPANTREE-7-BLOCK_PORT_TYPE : Blocking [chars] on [chars]. Inconsistent port type.
Explanation The specified interface has an inconsistent port type and is being held in a spanning-tree blocking state until the port type inconsistency is resolved.
Recommended Action Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected have the same mode (access or trunk). If the mode is trunk, verify that both interfaces use the same encapsulation (ISL or 802.1Q). When these parameters are consistent, spanning tree will automatically unblock the interfaces as appropriate.
