Cisco WAN :: Multicast On 4510 Core Switch And 3750x IDF Switches

Jul 15, 2012

At our site we have a 4510 core switch and 3750x switches in our IDFs. The 3750 switches are connected to the core via DOT1Q trunks in a server client setup. We are putting in an Informacast/Berbee server witch will send pages and text to the cisco phones. We also have 1 3750 switch connecting to the core via a layer 3 port channel. If we put the Informacast server on the phones vlan would I just need to enable ip pim sparse-dense mode on that vlan only and enable multicast routing, ip multicast routing?

Cisco Switching/Routing :: Connecting Core Switch To Firewall 3750x

Apr 13, 2013

I have a 3750X four-switch stack acting as the core of a fairly simple LAN. All I need to achieve (and this seems inordinately hard, but it is entirely likely that I'm just being dense) is to get access to the internet through my core switch, through the firewall and out through my VSAT. I've spoken at some length with the firewall providers (Cyberoam) and they tell me all I need to do when I migrate onto my new system (Cyberoam is currently in place at the entrance to our existing LAN) is change the local IP address of the Firewall, plug in the new switch to the LAN port, and away I go. Tried that, didn't work, so obviously I'm missing something.

Cisco Switching/Routing :: L2 Vs L3 Between 1002 And 3750X Core?

Feb 4, 2013

we are replacing network equipment at one of our sites. The network will have 12, 3750X switches(6 stacks) - one stack will be the core. A 1002 will be the WAN router to the Main campus. The 1002 will connect to the core via 2 ethernet cables. I'm debating whether to use L3 or L2 between the router and Core. I've heard that routing is more efficient if L3 is used and also I will be able to create an L3 etherchannel  between the 1002 and Core switch. See the attached doc.

Cisco Switching/Routing :: Multicast In A 3750x Stack

Jan 31, 2012

I recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.

Cisco Switching/Routing :: Multicast Data Drop On 3750X?

Apr 23, 2012

We are currently experiencing random multicast data dropouts on ports that are connected to a 3750X in VLAN ports. A test PC was connected to a routed port and we do not have any dropouts of the multicast data.We also took a 2960G and plugged it into VLAN ports on the 3750X.  Any test PC that is on the 2960G does not lose traffic. The traffic only drops on PCs that are connected to a port on the 3750X that is in a VLAN.  The data drops are random and last approximatly 55-59 seconds before we start receiving multicast traffic again.
I do not see any input/output errors on the interfacessh platform port-asic stat drop also show no drops
CPU runs at about 50% on the 3750X
Below is the configuration of the 3750X

Cisco :: Netflow Configuration On 4510 Switch?

Sep 6, 2012

I have a 4510 with sup7e and I would like to deploy netflow on this switch. The network will contain the 4510 switch where there will be 4 blades installed, each blade contains a separate Zone (vlan) . These 4 zones will then trunk upto a firewall via ten gig link over sub-interfaces. There will be an ip address assigned to each vlan on the 4500 switch but there can not be routing enabled between the vlans on the switch.

Cisco Switching/Routing :: 3750 Stackable Switches Etherchannel To Core Switches

Nov 18, 2011

If I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?

If I have two stackable switches were only one stackable switch has two uplinks one uplink goes to one core 6509 switch and the other uplink goes to the other 6509 core switch can a Layer 3 etherchannel be used if each uplink go to a different core switch, by the way hsrp is running between both switches and also can you give an example how data will be routed from the stackable switch through the ethernetchannel to one of the core switch accross the WAN to another core switch?

Cisco Switching/Routing :: 4510 PoE Switches Keep Failing

Jun 11, 2013

We have an issue where switches are failing weekly in a switch closet.  In the past month we have gone through several 3750G switches and a couple 4510s.  The power supplies have eventually made a popping noise and had to be replaced.  on the 4510s we've tried two chassis and gone through several power supplies.The switches have been behind UPS systems so should be receiving conditioned power.Could load from the PoE devices really be causing this?  I wouldn't think it's power since they are behind a UPS.

Cisco Switching/Routing :: 4510 - Setup Ports Between 2 Switches?

We have multiple switches(Cisco 4510, 4507R, 3560's) within our network. I've been looking over the port settings between them and noticed that not all ports that are connected directly from switch to switch are trunked the same. Some are desirable on one switch and forced truck on the other switch.

Cisco Switches :: Catalyst 4510 - Integrating SG200 Into Existing Network

Dec 17, 2012

We have an existing network with a Catalyst 4510 core switch and departmental 3560 switches connected via fiber. Due to company restructure we can no longer afford to buy new 3560's when anything goes wrong so this week I purchased an SG200-26 which I'm trying to get onto the network.
This is a legacy network which I didn't setup so my Cisco skills are somewhat limited (another reason for the SG200's hopefully), anyway have been looking at the configs on the existing switches and trying to match settings in the SG200 setup however not getting anywhere! I have the config from the dead switch so I can show what needs to be achieved, any experience in downgrading environment in a similar way?

Cisco Switching/Routing :: IP Phones Do Not Start After Rebooting (Switch 4510)

Oct 23, 2012

I'm having some trouble with a 4510 Switch Line Card. I need some recomendations for troubleshooting it.We have some PoE phones connected to the card number 3. When those phones were restarted, they did not go up again. In order to discard wiring issues, we connected the phone directly to the card 3, and the phone did not go up. If the phone is connected to a different card, it goes up correctly.

Additionally, to restore the service, these phones were migrated to other cards, but when we disconnect the equipment, ports in line card 3 remain in an up / up state (and nothing is connected to those ports!!), and only reflect the actual state after restarting the port.What steps could I do in order to troubleshoot this issue?. What should I look for, or how do I discriminate the problem? Might it be a hardware issue, a PoE issue?

Cisco Switches :: SG 300 10 Multicast With Multiple Switches In LAN

Jul 21, 2012

My internet router acts as an IGMP Proxy for the LAN and distributes IPTV there. The router is connected to one of my three SG 300 10 Cisco switches (connected to one another via uplink port). Now I want all switches to send multicast traffic to only the recipients of such traffic (PCs with VLC and Network Media Players) connected to either one of them. How do I have to configure the switches to do so and not flood the LAN with multicast traffic, is it enough to enable IGMP Snooping on each switch?

Cisco Security :: Catalyst 4510 / Switch Port In Dot1x Multi-auth Mode Stops Passing Traffic?

May 6, 2010

I am experiencing a problem on a Catalyst 4510 (cat4500-ipbasek9-mz.122-53.SG.bin) with 802.1x configured. Client PCs are connected via a mini desktop switch to a Cat 4510 switched port in multi-auth mode. The configuration of the port follows:
!interface GigabitEthernet2/34 switchport mode access ip arp inspection limit rate 30 authentication host-mode multi-auth authentication port-control auto authentication periodic authentication timer reauthenticate server dot1x pae authenticator dot1x timeout tx-period 5 dot1x max-reauth-req 6 spanning-tree portfast ip verify source vlan dhcp-snoopingend
It happens from time to time that the Cat 4510 port stops passing traffic. Reconnecting the mini switch recovers the communication. Client PCs connected to the mini switch seem to be authorized at the moment when the problem occures. The RADIUS Termination-Action attribute is set to RADIUS-Request. The problem is not present if "authentication periodic" is disabled.
