I think everyone should have experience in explaining technical terms to ordinary users who know nothing about I.T. So how are you going to explain the following terms to say....the HR manager in your company? 1) Hard disk & Computer (they always mix them up!) 2) router/switch/firewall (they...

Assuming your wife knows nothing about networking, how are you going to explain to her what a router/switch/firewall is?

I have a remote site (SiteA) that use IPsec GRE VPN to connect to the main site (SiteB) over the internet. Everything works fine and I have ACLs in the dialer interface that only allow IPSec, GRE and ICMP traffic in and out. However, whenever I apply or remove the ACL on the dialer interface...

We have 2 DC in different domain within the same forest. We setup 2-way trust between them and it works fine. However, if we reboot one of the DC, the trust will not automatically re-establish. We need to reboot the other DC also in order to automatically re-establish the trust. Is this normal...

I'm using Outlook 2003 and I have 2 ways to connect to my office: A) Broadband + VPN B) Dial-up + VPN Both (A) and (B) can ping the Exchange 2003 server IP address. However only (A) can send/receive emails. (B) can't contact the server and so cant send/receive emails. Anything necessary...

Problem 1: I got 2 PP8610 switches with 3.5.2 firmware. I use Device Import to import the 2 PP8610 switches from the ONMS DB. Well I can learn the interfaces using OPS but when I click the Server report page, the Policy Server said that these 2 PP8610 are not connected. I checked the Interface...

I got 6 8600 passports in the following config: A=B---Full-mesh-SMLT---C=D---Full-mesh-SMLT---E=F "=" sign is the IST link between passports. They are all inside the same Management VLAN. All passports have the same ro and rw SNMP community strings, and they are all having the same firmware...

I'm using 2 SS3 4228 which are stacked together and each has 2 GBIC ports (Port 27 and 28) Is it possible to configure an aggregated link using 1:27 (unit 1 port 27) and 2:27 (unit 2 port 27)? Or I must use 1:27 & 1:28/2:27 & 2:28 for the aggregated link? Thanks for help.

I'm going to configure a Cat3550 to use with a VPN gateway. Here is a very simple logical network diagram: VPN_Client<--ISDN-->Router_A | |--VLAN10 | VPN_GW |...

I'm going to create 4 vlans in a 3550 switch and I want to configure intervlan routing between only 3 of them. Is it possible? If yes then how to configure? Thanks.

The software version of our switch is v2.03, model is SS3 4228G and also 4250T. We've set a management ip in the 4228G/4250T switch and we used all the factory default settings. Then we connected an IBM notebook to the switch FastEthernet port using a straight cable. We started the ping on the...

I want to know the behaviour and mechanism of the stacking. What does it do actually? Does it just simply form a single logical switch unit or can it share memory and cpu resource among the switches? And what if one of the switch goes down? Will all the ports in that switch go down too? Thx for...
