Cisco Switching/Routing :: Can LLDP Be Disabled On SGE2000 Switch

May 2, 2013

I 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.

Cisco Switching/Routing :: LLDP Chassis Discovery On Nexus 5548UP?

May 1, 2012

I'm seeing several error messages like these in the logs of my Nexus 5548UP switches.

2012 Apr 24 16:39:41.470 SSV_5K_SW2 %LLDP-5-SERVER_ADDED: Server with Chassis ID aaaa.bbbb.cccc Port ID mgmt0 management address X.X.X.X discovered on local port mgmt0 in vlan 0 with enabled capability Bridge
 
2012 May  2 05:05:00.627 COR_CCO-NX-5548-UP_01 %LLDP-5-SERVER_REMOVED: Server with Chassis ID aaaa.bbbb.cccd Port ID aaaa.bbbb.cccc on local port Eth1/1 has been removed
 
2012 May  2 05:06:40.328 COR_CCO-NX-5548-UP_01 %LLDP-5-SERVER_ADDED: Server with Chassis ID aaaa.bbbb.cccd Port ID aaaa/bbbb.cccc management address NIL discovered on local port Eth1/1 in vlan 0 with enabled capability None
 
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.

Cisco Switching/Routing :: LLDP-MED TLV Commands - Cat45010+E Sup7 And Polycom CX600 Lync Phones

Oct 15, 2012

I'm trying to configure LLDP-MED between a Cat45010+E Sup7 (IOS 15.1) and Polycom CX600 Lync phones. I have created and applied the correct network policy for the interfaces.
 
From these sites, I need to send all the correct TLVs or the phones won't respond: {URL}.
 
When a scour the config of the switch, I can't find any related configuration commands relating to the specific LLDP-MED TLV components which are enabled/disabled. Where are they hiding? I would like to confirm which TLVs are being sent by my switch and if they are matched to the phone. I can always use the DHCP method, put this is not preferred.

Cisco Switching/Routing :: C6509 To Have Feedbacks About Vss Availability

Mar 9, 2012

we plan to implement VSS on our datacenters (C6509/Sup720), in order to remove L2 loops (currently, access layer are C3750 stacks, which could evoluate for N5K/N2K). I would like to have some feedbacks about VSS stability. Some years ago, I have seen some bugs with this technology in another company, so I am still not totally comfortable  to use it in the datacenter.

Cisco Switching/Routing :: Access Layer Switching With 2960 / 3560x / 3750x And 4506

Jan 17, 2013

My management has tasked me to give them a high level overview of the different switching we can choose for our new building.
 
This is what I know so far.4 Closets, each closet has 450 ports,One MDF room that is will contain one UCS Chassis and a Nimble iSCSI SAN.
 
I am working on the spreadsheet and it looks like this (Not totally filled):

Cisco Switching/Routing :: InterVlan Routing With 3750 And 2960 Switches?

Nov 21, 2012

I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)

Cisco Switching/Routing :: 2960 / SG 300 Switch - VoIP Setup - Asymmetric Routing Not Working

May 21, 2013

I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
 
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
 
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
 
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
 
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
 
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.

Cisco Switching/Routing :: 2960 What Can Block ARP

Feb 23, 2012

We recently updated a site2site link to metro ethernet, ISP call it 100mbps LAN Extension, but to me it is just QinQ over fibre connection. Most went well, one thing (annoying to me) is we can not ping our switches on both ends anymore.
 
We have a 3750 in headend and another 2960 on the other end. I used to be able to ping/telnet to the management IP from one to the other. Now we can not. I think the ISP is applying some configuration on ports of their customer-premises equipments (both are Cisco switches) but agent in ISP told me no. I thought there is some configuration on Cisco switch to block "MAC discovery" but i just can not remmenber what was that and google also failed me this time.
