We are using a ShoreTel system. It replaced our Cisco CallManager Express installation a while ago. ShoreTel is cheaper, has more functionality "out of the box" and is much easier to implement and maintain. I'm very happy with it. *Rob

Last time I tried this, I used Cisco VPN Client version 4.6. Could you try it with a newer client?

As NetworkGhost briefly stated, there is an issue with PDM and newer java runtime versions. I assume you have the latest jre installed and this won't work with PDM versions 302 or lower. You should upgrade PDM to 303 (or higher - I think 304 is curent). In case you cannot upgrade, you need to...

Well, the problem is: you do *not* get any "password expires in..." warnings when you connect through the VPN client and you are just locked out when it happens. Home office workers typically run into this issue. But there is a mechnism to let you change your password from the VPN client in...

Well, W2K calls it NTP, but it really is SNTP. SNTP is a small subset of NTP and is upward compatible, i.e. an SNTP client can get the time from an NTP server. The other way - NTP client get time from SNTP server - does NOT work. Unfortunately, W2K only implements an SNTP server and your...

The VF45 fiber connector is part of the Volition cabling system by 3m. You can get more information from http://www.3m.com/volition/index.jhtml VF45 went out to become the new standard fiber connector, succeeding the bulky and expensive SC-Duplex connector. But it didn't make it. SC is still...

Exactly one hour. The description of sysUpTime is: The time (in hundredths of a second) since the network management portion of the system was last re-initialized. Cheers *Rob

Glad I can help. Here is a "starter" for your Linux box: Check if routing is enabled: cat /proc/sys/net/ipv4/ip_forward 0 = disabled 1 = enabled Enable routing: echo 1 > /proc/sys/net/ipv4/ip_forward List all active interfaces: ifconfig Create new subinterfaces and give them IP...

Don't mess around with VLAN tagging if you don't need VLANs. Enable Spanning-Tree instead to prevent loops and the resulting broadcast storms which are the most likely cause for your network problems. I guess you have more than one connection between the two switches. Stacking the 2600 switches...

That's interesting. I didn't know the 7960 supports telnet - and it doesn't work on mine (connection refused). I'm running P00303020214 image. But I can connect it with a web browser and get all the settings and statistics displayed. Cheers *Rob

I do this with an old Cisco router (2503) I have hanging around. The Ethernet interface of the router is connected to a hub and this hub is my "test-internet". I just have to configure the "official" IP addresses I need for testing as secondary addresses on the router's Ethernet interface. You...

Yes, the cluster command switch is the only one that needs an IP address. Cluster members are identified by their MAC addresses. You can configure a cluster from the command line, but I don't know the commands off the top of my head. I'd go this way: Assign an IP address to the switch that is...

Changing the IP address is simple. Just connect to the serial console port and press Enter. If you get "Password:" enter the access password. Anyway, you get a prompt> > en Password: <enter enable password> # conf t (config)# int vlan1 (config-if)# ip address 172.17.x.y 255.255.0.0...

Disabling fax relay just prevents the router from re-coding the fax signal into fax messages and back. This means, that the fax signal is sent as voice packets and therefore is impacted by jitter on the VoIP transport. I don't know of any way to automatically disconnect the call, when a fax...

It could be an auto-negotiation problem between the 3Com card and the switch, resulting in a full/half-duplex mismatch. If the switch is manageable try setting the port to 100half. If not, try to set the 3Com card to 100half (you'll need the driver and diagnostic utility from 3Com, not the...

On the Cisco, configure the interface connected to the BayStack as static dot1q trunk. Something like switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate On the BayStack, create VLANs with the same ID's as on the Cisco (10 and 20 in your example). In the Port VLAN...

For traffic statistics I use a combination of MRTG (SNMP backend), RRDTOOLS (database) and Routers2Cgi (frontend). My favourite sniffer still is Ethereal. All OpenSource and available for Linux and Windows. Cheers *Rob

HP Top Tools" have been replaced by "HP ProCurve Manager". Less complicated and less resource eating. Still comes for free in a limited, but very useful version. You can upgrade to "HP ProCurve Manager Pro" for a small price to get full functionality like VLAN management. "CiscoWorks for...

You have to watch out for the spanning tree forwarding delay. See http://www.cisco.com/warp/public/cc/so/cuso/epso/entdes/hsrp_wp.pdf and especially http://www.cisco.com/warp/public/619/8.pdf to avoid problems. *Rob

If the HP port really was configured for 100full it wouldn't report collisions, since they are not possible on a full duplex link. Late collisions on a switched TP link can only occur if there is a duplex mismatch, i.e. one side runs half duplex, the other side runs full duplex. Please double...
