Native VLan on acess switch

[rohit.kulkarni]

I've 7 accesss switches from which one switch is connected to 2nd switch with RJ 45 Trunk and other switches cascaded with eachother.

My question is ,Is native vlan necessary on all access switches, if yes than ?

Overview:SW1-Trunkport Fa0/1 to SW2-Fa0/13.

SW2-SW3-SW4-SW5-SW6-SW7(Cascading).

SW4-Connected to core switch Trunk port.

Encapsulation type is dotlq and the cascaded switches are in half duplex but the switch that has the RJ45 trunk connectivity with 2nd switch is in Auto duplex and the connectivity for core switch is also in Auto duplex from one of access switch.

Is that affecting speed?

Ah, you have a CX_GIGASTACK

From

http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800a2cac.shtml

"GigaStack GBIC supports one full-duplex link (in a point-to-point link), or up to eight half-duplex links (in a stack configuration) to other Gigabit Ethernet devices."
