Hello All, We are trying to setup datacenter for newly opened office and trying to find out the difference between WS-C2960X- 24TS-L vs WS-C2960X-48FPS-L.
Could any of your throw light on how to choose between the two mentioned switches?

how to configure the intranet

peterson123456 — Fri, 06 Mar 2015 17:53:59 +0800

I was a green hand on Cisco networking, and have purchased a Cisco 871-K9 recently for reserch from www.3anetwork.com. I have configured SDM and CCP, but cannot configure PPPoE, only have DOS configuration and finally I can configure the PPPoE for the extranet, but i don't know how to configure the intranet, who can tell me? And attached my configuration, 0-3 port for LAN; 4 port for WAN. My attention was 192.168.1.1 for gateway, intranet DHCP 192.168.1.100~192.168.1.253, dailing was WAN port, while the problem was, the IP address cannot be get for intranet, and the IP manually specifying was 192.168.1.100, the data cannot be received, was 0, network cannot work.

Huawei OLT

We have 2 power cables with the Huawei OLT. Now I have some question about it, do we have to put 24V/20A on each cable or 48V/20A on each cable? Can we use only one cable or must use both? Can we use one power unit with a single 48V/20A output for both entries in the OLT?

CISCO2960S switches

peterson123456 — Wed, 14 Jan 2015 17:28:06 +0800

i wanna make sure, vlan which can set ip address is 3 layers, otherwise layer 2, is this correct? CISCO2960S can set the interface vlan address, CISCO2960S are layer 3 switches?
