Cisco Switching/Routing :: Turn On LLDP On 1861 Router / Switch?
May 27, 2013I have not been able to find the option to turn on LLDP for our Polycom (Lync) Phones. Is this not an option for this model router (C1861)?

Cisco Switching/Routing :: Can LLDP Be Disabled On SGE2000 Switch
May 2, 2013I just want the switch to be quiet so that I can perform some network testing with only the connected hosts showing up in my traffic analysis program. But every 30 seconds or so the switch sends out an LLDP packet. This switch is only used in the lab for running tests so I know I don't need the LLDP feature running.
This article explains how to disable LLDP globally on a Catalyst switch, but I can't find any option to disable LLDP in the SGE2000's configuration menus.

I will say that these 5548s are serving as the distribution layer for a UCS chassis (2x 6120 FIs) but didn't know what kind of visibility the Nexus would have into that - the chassis keyword is what's alluding to this in my mind, and I'm seeing these messages whenever interfaces that connect downstream to the fabric interconnects are brought up or down.

Dec 15, 2009One of my engineers issued a command to turn off port security on a number of ports using the range command. The command failed on the first attempt due to a tacacs auth failure which I suspect is due to a low tacacs timeout value. The engineer then reduced the number of ports in the range command and re-issued the config change after which the switch just crashed and rebooted.
The logging buffer on the switch displays the following:

Cisco Switching/Routing :: 3560 VLAN Routing Between Switch And Router
May 8, 2012I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?

Cisco Switching/Routing :: Using Built-in Switch On 1801W Router?
Apr 3, 2013I have a Cisco 1801W router, running a DSL connection with wireless connectivity for a school. This is configured on the fastEthernet0 interface on the 192.168.1.0 network (the router is 192.168.1.1).
I was wondering if it is possible to get the built-in switch (fastEthernet 1-8 interfaces) to be used as a part of the same network (192.168.1.0/24).
Fastethernet0 is connected to the school's main switch (24 port), but we could use a few more ports. I'd love to use the 8 ports on the router.

Cisco Switching/Routing :: 3560 DHCP Between Switch And Router
Jul 23, 2012I have a cisco 3560 24PS and its connected to two ADSL broard band routers.one is a personal broadband line using a Billion ADSL broadband router, and the other is a business broardband line using BT's 2wire broadband line.on the Billion routers i have various things attached like a NAS and a printers, both wired connections. then i have laptops and phones that connect over wifi, so its configured to act as a DHCP server
the only thing conncted to my 2wire router is my company's laptop (wired or wifi depending on where i'm working from), so again i have it working as a dhcp server.The switch is configured with multiple vlans, with dhcp scopes assigned for each vlan.I have a static route pointing all traffic to my Billion ADSL for internet connectivity.
The problem i'm having is that when i turn on the cisco switch, all wifi conected devices loose their conection. only 2 things get it working again, a reboot of the router, or disabling then enabling the DHCP service on the router.upon further analysis i was able to find out that the devices were not able to pick up an address from the router. again i looked deeper into this and i can see the following on logs of my router: [code]
so it seems that the router tuns off its DHCP capabilities because it detects that my Cisco switch is running DHCP services. I need to figure out how to keep the billion routers DHCP running when ever the switch is turned on.is there a way of filtering out any DHCP chat from the switch to the router?

View 3 Replies View RelatedTurn Server 2012 Into A 10G Switch
Mar 7, 2013I have some unused 10G NIC's and want to see if there's a way to install them into a computer and turn that PC into a switch. I need to run Windows based software for driver support of the NIC's, such as Server 2012. This is a picture of what I am hoping to accomplish:
[PC1] -----10G------[PC2]------10G------< Hardware Switch >
| | | | |
1G 1G 1G 1G 1G
| | | | |
[PC3][PC4][PC5]......
As you can see in the simplified picture above, I have a real switch which has a single 10G link that is connected to PC2. I would like to add the 10G cards to PC2 so that I can create a "switch" of 10G ports on PC2 which I can then hook up other clients (such as PC1 in the above picture).
PC2 needs to provide network access and internet access to PC1 (and other PC's connected to PC2 - not pictured).
The rest of the clients on the network are connected to the regular gigabit ethernet ports of the hardware switch (including my router which is 192.168.1.1).
I looked into Windows Internet Sharing, but for that to work, I need to connect the router to PC2 above and for other considerations not described above, it is not physically possible for me to do that.
Is there software I can run on PC2 that will turn all the NIC ports of PC2 into a "switch"?

Is there any difference between these two switch modules? or are they the same and the more expensive "P" version is simply supplied with the ILPM-4 daughter card for POE?

Cisco Switching/Routing :: How Switch Module Works In 2911 Router
Sep 4, 2012 how this switch module works in 2911 router? I have two 2911 routers in HSRP configuration for redundancy with crossover cable between switch modules. OSPF running on routers.If active router loses its power and then comes back again, it boots first, its internal link to switch module comes up and it starts to forward packets to switch module. The switch module starts to boot only after router is ready. So I have outage of about 3-4 minutes. For our real-time applications it is way too long.
any way to start booting of the switch module before router gets ready?I understand I can boot it manually, but it is only after router is ready. Only way to get around it I found is to disable internal link and use router interface to connect to the switch module.
