Cisco WAN :: Interface Netgear Smart Switch To 881 LAN Port
Dec 16, 2012we have 100 Cisco 881 routers in our network and they all work fine to Linksys, 3Com, etc switches. The problem we have encountered is interfacing to Netgear switches. Netgear switches use autosensing on their ports and it does not seem to be compatible with MDIX autosensing on the Cisco 881 4 port LAN hub that is standard on the 881 router. Would a cross over cable resolve the problem? Since both run autosensing MDIX they never synch - so likely a cross over would not do much. I see this with all types of Netgear smartswitches. If you put a small switch between the Netgear switch and the 881 Cisco router everything works fine except for getting port 9000 traffic through.

May 29, 2011I have a small, simple small business network. There are 2 switches - an 8-port switch connected to my main Windows server (which is the DHCP provider for the network), and a 24-port switch which is plugged into the 8-port switch.
I replaced these switches (Dell unmanaged switches) with the Cisco 200 series smart switches (the 8-port and 26-port models). When I plug the 26-port switch into the 8-port switch, it is unable to get its DHCP address from the Windows server. Also, any device plugged into the 26-port switch cannot communicate with any other device, and all of the ethernet port lights flash at the same time at the same frequency - quite a light show!
If I plug the Windows server DIRECTLY into the 26-port switch it receives a DHCP address.
I have tried a 2nd Cisco 26-port swtich and it does the same thing, so I assume it is not a hardware issue.

Nov 12, 2012I'm searching for a managed switch that allows me to not only mirror a port/ports, but also to still use the destination port for the mirrors as a link to the internet/the rest of the network. Aside from this, I still need the VLAN functionality of good switches, and ideally PoE provided, too.
I have seen the majority of the features of this in the NETGEAR GS108E (http:url...), but this doesn't provide PoE to the ports and also requires Windows to log into.Is this a feature of many switches? I can think of many snooping applications where it would be incredibly useful.

Oct 16, 2011We just purchased 8 managed switches POE to swap out our existing in preparation for our new phone system. We installed them all after configuring with static IP. Deployed... and all but two work fine. Any tips for troubleshooting why two of them do not work? There are a couple other switches in the building. Could it be that a switch "upstream" from the two non-functioning switches is causing an issue? If so, how do I find out? When we put back the two "dumb" switches all was fine.

Cisco Switches :: Configure SRW248G4 Switch Through Console Port?
Jun 2, 2013I want to configure my SRW248G4 switch thru console port. Unfortunately in this switch there is no RJ45 console port input, I can only see cosole port that is look like RS232 input. I bought two standard cisco console cables that have one end with db9 and one with RJ45.
Now I have and idea to put one end of one cable (db9) to switch, and one end (db9) of second cable in my computer (COM input/output)
I need to connect two RJ45 together - this is not a problem, I know how to do this. Here is the question :I know how pinout in my computer look like but i can't find pinout of console port in my SRW248G4. There is many pictures in Internet, for many Cisco devices but this isn't working. Maybe in LINKSYS pinout look different ?

Cisco Switches :: Get InterVLan Routing To Work On DF300- 24 Port Switch
Jun 2, 2012I am trying get inter vlan routing to work on a DF 300 - 24 port switch. I have an existing company network on 192.168.111.0 and want to create a vlan on 192.168.1.1 that can talk to 192.168.111.0. I have enabled layer 3 routing on the switch via console and also provided the ip routing command. I have the following VLAN's:
VLAN1 - Default 192.168.111.0
VLAN2 - 192.168.1.0
I have enabled DNS and provided my two DNS servers 192.168.111.82 & 192.168.111.212. I have set the VLAN1 interface to 192.168.111.217 and VLAN2 interface to 192.168.1.1.
Ports FE1 - FE15 are set to access ports and assigned to VLAN1 (untagged)
Ports FE16 - FE24 are set to access ports and assigned to VLAN2 (untagged)
I have set a default route for the switch to 0.0.0.0 0.0.0.0 192.168.111.254 (Draytek 2600 router). I have connected a computer (A) to VLAN1 port FE3 and a computer (B) to VLAN2 port FE16. I have set Computer A default gateway to 192.168.111.217 and its IP address to 192.168.111.94. I have set Computer B default gateway to 192.168.1.1 and IP to 192.168.1.2.
Computer A has access to Mdaemon, file server via network drives but no internet (cannot ping google) and can ping computer B and RDP onto computer B.
Computer B can ping computer A and RDP onto computer A but does not have access to the company network i.e MDaemon, file server etc. It also cannot access the internet.
From the console I can ping [URL]and all ip addresses in the company network i.e. 192.168.111.82 (DNS server). If I scan computer A wirh wireshark the internet starts working weird!

Cisco Switching/Routing :: IPv6 Filtering / Policing On 2960 Switch?
Jan 3, 2012Trying to control capacity utilization for guest users connecting to a 2960 switch. No problem for IPv4 users, but IPv6 is giving me fits. What I've found out by trial and error so far implies that there is just enough IPv6 smarts in a WS-C2960-24TT-L running c2960-lanbasek9-mz.150-1.SE to make it impossible to control IPv6 traffic. Blocking IPv6 would be sufficient short term, but MAC filtering on type 0x86DD does not appear to work either. Here are the results I've gotten so far:
What "works":
* Protocol ipv6 or an IPv6 ACL in a class map.
* Using a class map referencing ipv6 protocol or an ipv6 ACL in a policy map.
* IPv4 inbound filters and policing.
* Blocking of IPv4 traffic by a MAC ACL blocking type 0x0800 (IPv4) - note that the docs explicitly state that MAC filters do NOT filter IP traffic, except for on this box on this release they do.
What does not work:
* Applying a policy map referencing a class map referencing protocol ipv6 or an IPv6 ACL to an interface. The service policy is accepted by the parser, but is not inserted into the running configuration.
* "class-default" in a policy map only matches IPv4 traffic, not all other traffic.
* Blocking of IPv6 traffic by a MAC ACL blocking type 0X86DD. No problem applying the access-group to the interface, it just doesn't do anything.
I am aware that this box is not supposed to support IPv6 other than for multicast, but as implemented, this is a hole an abuser could drive a MAC truck through.
My questions:
Is this situation unique to this particular 2960 switch or SW release (I also tried 12.2(58)SE2) or does it afflict all 2960's running LANbase?
Assuming the answers to the first two question are negative, what is the minimum requirement to get working IPv6 policing in an edge switch?
Cisco Firewall :: ASA 5505 URL Filtering Using URL Filtering Server?
Feb 7, 2012I have come across articles mentioning that URL Filtering can be implemented by using ASA 5505 with URL Filtering Servers. But Websense and other Web Filtering Servers are paid ones ? Are there any free solutions available ? What exactly is N2H2 ? The reason is I don 't want to increase the CPU utilization of ASA by implementing URL filtering within the device. If I have around 30 nodes which connects to the internet via a 2Mbps line through ASA 5505 and if I want to block around say 10 or 15 URLs , will it increase CU utilization beyond permissible limits ? Currently the CPU Utilization is around 10 - 15 . Here's the infrastructure setup .

Cisco Switches :: SGE2010 Switches / VLANs And A Blocked Port In Spanning-tree?
Aug 20, 2012I have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
Cisco Switching/Routing :: Convert Switch Port To Router Port On 6500
May 8, 2012On the supervisor card of a cisco 6500 series, according to the following link, [URL] it only has 2 uplink ports on the card. Would I be correct in assuming that I only have those to ports that I can configure IP addresses on?
The cisco that is being devlivere is coming with a 48 port switch and 24 port fibre switch. Could I change any of those ports into a router port and configure IP addresses on those?
The supervisor card is a ws-sup-720-3b the 48 port switch is a ws-x6748-ge-tx the 24 port fibre switch is ws-x6724-sfp
Cisco Switches :: Reconfigure Port Mirroring From Port FE17 To FE3 / SF200 Web Interface Crash

Cisco Switching/Routing :: 3825 ISR - Traffic Route From Switch Port To Router Port
Jun 5, 2013I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level. I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other. I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it. This seemed to allow devices connected to the switch ports to talk to the built-in router ports. I thought this was all making sense until i applied an access-list to the router port. It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere. I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port. However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully.
It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.
