Cisco WAN :: 4506s - Switch Virtual Interface (SVI) Versus Routed Physical Port
Feb 28, 2012What are the pros and cons of configuring a Switch Virtual Interface (SVI) versus a routed physical port between layer 3 switches?For example, if I have two 4506s and have a need to run HSRP and route between them which feature is better and why?

View 2 Replies View RelatedCisco WAN :: 877 - Virtual Interface Goes Down But Not Physical Interface
Apr 5, 2011I have five 877 routers connected to ADSL circuits provided by Vodafone. Each has a VPN tunnel back to a PIX.
Occasionally one of the sites will lose it's connection to the PIX.
When we check the log, we find entries like these:-
Apr 5 01:31:54.085 UTC: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access2, changed state to downApr 5 01:33:19.344 UTC: %CRYPTO-
[Code].....
As you can see, the physical interface (ATM0) is not being reported as changing state to down, neither is the Dialer interface.
When the router is in this state we have to SSL to the public IP address of it and manually restart the ISAKMP SA.
When the router sees the ATM interface go down and subsequently come back up, the VPN connection to the PIX also recovers.
So - in a long winded way I think I'm asking....why does the Virtual interface go down and is there anything I can do to stop it happening?

Hardware Version : V1

When using the USB printer port share function, I found that some PCs, which had never physically connect to a USB printer before, will not have the virtual USB printer port in the port selection. In this way, TP-Link's USB printer controller will not be able to setup the connection. The PC will not be able to use the shared printer from my WDR3600.how can I create a virtual USB printer port in the remote PCs (without need to physically connect a printer to them) or other method to use the shared printer?

Jun 12, 2013I have a laptop here that I can't seem to turn wireless off on via the switch. While the obvious choice is hardware failure, it's nearly a brand new Dell Precision M6600 and I hesitate to jump to conclusions.
The physical switch on the system will not toggle wifi on or off; it is always on. I can disable it via Windows (Win 7 Pro), or simply disconnect from the network, but when I do it does not remember the wifi passwords, which may be a separate issue.

View 5 Replies View RelatedCisco Wireless :: 1252 - Create Multiple SSIDs?
Sep 10, 2012Currently my company has 1 primary SSID that is used throughout both floors of the building. We have 1252 LAPs which have 2.4 and 5Ghz antennas. I'm not sure if this issue is only with XP or perhaps it's the computer's drivers but we run into problems with end users going to a different location and having a very weak signal or nothing at all, yet coverage is fine. I believe the problem is the end user's machine selecting the strongest signal and it I have the feeling that switching bands isn't being done as it should when it's in range. So my question,
Should I split up our 1 SSID and created multiple SSIDs according to the location and include 5Ghz or 2.4Ghz in the SSID name so it's easier to ensure that users are connected to the proper signal? I want to ask if multiple SSIDs would still enable users to freely roam (as long as the ssids are configured) throughout the building without noticing a loss of signal but currently just having 1 SSID isn't really enabling people to freely roam around without connection issues.I don't believe having multiple SSIDs will be useful for the computer's choose their connection any more efficiently but allowing the user to manually see what they're connected to and pick something better according to their location.
Cisco VPN :: WRVS4400N - ASA Cannot Create Multiple Tunnels To Same Peer Address?
Jun 23, 2012We have several remote sites with Linksys WRVS4400N and Smoothwall firewall/vpn devices. I need these sites to be able to connect to multiple dis-contiguous subnets at our main office. This was easily done with smoothwall and linksys. You create a separate tunnel for each subnet and voila, you're done. However, when I tried this with our newly installed ASA, it will not let me create multiple tunnels to the same remote peer address. This is a problem since these sites only have a single static public IP address. Am i missing something or does the ASA not allow connections to/from multiple subnets form a site with a single peer address?

Secondly, after creating the first tunnel i am able to access the remote lan network but when i tried tracert "remote lan ip of a pc" from my pc i got "request timed out" after passing my 837 but succeeded to reach the target. Does tracert needs something to be opened in the router?

Cisco WAN :: 3550 Port Forward Down Through Layer 3 Switch
Aug 18, 2011I'm looking at implementing a cisco 3550 Layer 3 switch and would like to know if i can forward ports down to all of my different Subnet Servers/Pc's.

May 21, 2012i have an OM1 MMF fiber run between two switches, the first being a 3750 and the second being a 3550.
The link currently exceeds the maximum distance for OM1 @ 1000Mb/s (220m) so i would like to downgrade the link to 100FX using the necessary SFP's/GBIC's to extend the maximum distance to 550m and run the link @ 100Mb/s.
I have the part code for the 100FX SFP to install in the 3750 (GLC-GE-100FX) but cant find a 100FX GBIC for the 3550, can I use a 1000SX GBIC (WS-G5484) for the 3550 at one end and the 100FX SFP at the other? Any success with this configuration over MMF?

Cisco Switching/Routing :: Port Unreachable Messages On 3550 Switch?
Jan 24, 2012While working at a client site today, I was troubleshooting some ICMP connectivity for a network we have created.I turned on 'debug ip icmp" on the 3550 switch int he middle, and was inundated with the following debug output:
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5

Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
[code]....
This output fires several times a second, and based on how often it is firing, I am curious if it may be a culprit with respect to the fact that the client has indicated that they have some slow internet.Should the next step be to look at the workstation at 172.16.1.5?
