Cisco Switching/Routing :: 6513 Do Traffic From Each VM Going In / Out Of Nics In VPC Use Both Physical Links

Sep 28, 2012

WE got our ESXi servers recently moved from a 6513 to nexus 2000 FEXs uplinked to a nexus 5000s basically we have enhanced vPC and nics goin to 2 different FEXs and they uplink to 2 nexus 5000.
 
the Vswitch for VMs is setup in a VPC. Question is do the traffic from each vm going in/out of these nics in a vpc actually use both physical links? How can i tell from the switch?

Windows 7 Routing Traffic Between NICs

Mar 21, 2012

I want to route traffic from nic 2(192.168.2.1) to nic 1(192.168.1.1). In lame terms route the traffic from 192.168.2.10(gateway 192.168.2.1) to 192.168.135(192.168.1.1). I know how to use the route command in CMD. So how would I get the traffic from 192.168.2.10 to 192.168.1.135? I'm just not sure how I would do that with the route command. I've tried

Code:

route -p add 192.168.1.135 mask 255.255.255.0 192.168.1.1 IF 12

Also tried like 5 different ways The IF 12 is my NIC 2.

Server With 2 Nics Routing Traffic

Dec 1, 2011

So i have a server with an internet nic and lan nic. The internet nic gets its IP from the router 192.168.1.7 the lan nic uses DHCP for the network and has 172.16.1.1. I just turned on the ftp service and it works fine in the lan side but cant reach it from the ISP side. I use a dynamic dns host which is monitoring my internet ip and is correct.

Routers / Switches :: Routing Traffic Across Nics From One Subnet To Another?

Sep 25, 2012

I have an issue with some traffic routing:

Machine A | Machine B (Win 2008 R2) | Machine C

Start: 192.168.5.9 > 192.168.5.5 (NIC 1) - 10.14.137.130 (NIC 2) > 10.14.137.128So the question is how do i get traffic from Machine A to Machine C. I've tried various 'Route ADD' cmds but no luck so far. So was hoping someone out there could shed some light for me?Machine B is a AD/DNS and can talk to the entire 10.14.137.x range but has no forwarders set up in DNS. And does not act as a AD/DNS server for the 10.14.137.x range. It fills these roles only for the 192.1668.5.x range.

Cisco Switching/Routing :: 6513-E / 6513 And WS-X6748-GE-TX Compatibility

Oct 29, 2012

we have a chassis 6513-E and a module WS-X6748-GE-TX, I'd like to know if could I put this module in any slot, since the documentation from Cisco says that any slot from a chassis 6500-E Series can support this module. And then in the documentation of WS-X6748-GE-TX says that this module is not compatible in the slots 1-8 of the 6513 chassis, only from 9th to 13th slots, in those slots from the 6513-E we already have 4x WS-X6748-GE-TX, and we'd like to know if could we put the module in the rest of the slots. The 6513, and 6513-E is kind of confusing.

Cisco Switching/Routing :: 2224TP / Servers With Dual NICs Connected To Separate FEXs

Mar 26, 2012

Our current topology is a single N7K with two 48port 10Gb F2 linecards and FEX 2224TP in the server racks.  In a few of the racks that house important servers, we have placed dual FEX 2224's.  Each FEX has 2 10Gb links back to the N7k (each link on a separate LC).  I've tried to create a port-channel for the important servers in such a way that each NIC on the server is connected to a separate FEX - but its failing (simple drawing attached).  I've read multiple posts saying this is possible, and others that say its not.  I've also submitted a TAC case and have been told it's impossible to port-channel interfaces on separate FEXs connected to a single N7k - but I find this an impossible limitation and want to verify it's actually right.  Is this really a limitation?

Cisco Switching/Routing :: Nexus 7010 / 5510 - Run OSPF As Layer 3 Routing Protocol Between VPC Peer Links

Mar 25, 2012

I have an environment where i have two nexus 7010 switches, along with 2 nexus 5510's. I need to run OSPF as a layer 3 routing protocol between the vpc peer links.  I have 1 link being used as a keep alive link, and 3 other links being used as a VpC link.
 
1) Is it best to configure a separate Vpc VLAN i.e 1010

2) Is it best to configure a vrf context keep-alive

3) just have the management address as the peer ip's.

Cisco Switching/Routing :: 3750 / MST Pre-standard And Links Down

Sep 3, 2012

Checking the logs we have seen the following messages: 
 
%SPANTREE-3-PRESTD_NEIGH: pre-standard MST interaction not configured (Port-channel3). Please, configure: 'spanning-tree mst pre-standard' on ports connected to MST pre-standard switches.
%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel3, changed state to down
%LINK-3-UPDOWN: Interface Port-channel3, changed state to down
%LINK-3-UPDOWN: Interface GigabitEthernet1/0/1, changed state to down
%LINK-3-UPDOWN: Interface GigabitEthernet2/0/1, changed state to down
 
When this happened, the interface that was actually blocked by STP didn't come to forwarding state, and as a result this switch became isolated.This switch is connected to a switch that runs standard MST, and to some switches that run PVST but have bpdufilter enabled as we don't want them to participate on the STP. It is a 3750 switch with software version 12.2(55)SE5.
 
 As far as I knew, when a MST pre-standard BPDU was received, the interface was able to receive more pre-standard BPDUs, but I didn't know it would turn the link down. Why the links went down, and if there is any way we can configure those links to accept only MST standard BPDUs.
 
I would also like to know if there is any chance a switch running PVST can send a MST pre-standard BPDU if it has a software version 12.2(25)SEE3.

Cisco Switching/Routing :: Nexus 5548UP - (Physical Address Changes) Messages In SolarWinds

Dec 9, 2012

We have recently upgraded oor LAN and we are using couple of Nexus5548UP switches in the core with 2960 stacks as access switches. Each access switches stack is connnected to both core switches with link being port-chanels and VPCs. All is working fine, but our SolarWinds management platform (NPM) is being flooded with "Physical Address changed" events. Here is an example of messages:
 
NSW_Core_2 - Ethernet1/7 Physical Address changed from 000000003811 to 73616D653811
NSW_Core_2 - Ethernet1/7 Physical Address changed from 200B82B43811 to 000000003811
 
For each interface I have messages like these repeating.I am not sure what those messages means or if there is actually anything wrong. Performance of the network is good, there are no errors on any interfaces and I do not see anything related in the switch loggs.

Cisco Switching/Routing :: Configure Port-Channel Or Physical Interface On 3750

Jan 12, 2012

how to configure this. I did it in the past but kind of forgot how I did it.I have a stacked 3750 (two physical switches) connecting to a 2960.
 
I am creating trunk ports with limited access to VLAN 300, 600, and 700.
 
There is two interfaces connected from the 3750's(one on each physical stack member) to the 2960.I have the physical interfaces configured exactly the same.
 
3750 Config:
 
interface Port-channel2
!
 interface FastEthernet1/0/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1, 300,600,700
switchport mode trunk
speed 100

[code]....

Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.

Cisco Switching/Routing :: Unable To Console / Ssh To 6513

Aug 9, 2012

I have a 6513 with redundant sup 720-3B's that I cannot get onto.  In short, one of the power supplies failed, it still passes traffic but I can't console or ssh to the box.  Other than the two sup 720's, I have a 4 port 10gig card, a 16 port GBIC Card and an IDS module.  I have tried removing the 10Gig, IDS and one of the sup's but still don't get anything on the console.  I have rebooted the entire chassis and don't get anything on my console while booting.  I have tried changing the speed of my terminal to every setting available incase someone has changed it at some stage but to no avail. I have tried swapping sup's, using only one at a time in the chassis but not getting anything. Is there anything else I can try to get onto this chassis?  The power supply is a 3000w with a 32amp input.  The failed power supply had tripped a switch, when i brought it back up, the power supply came out but the output failed LED is on. My #questions are, is there anything else I can do to try get onto the console, and is the power supply goosed when the RED LED is lit?  I have reseated the power supply also but the same result.

Cisco Switching/Routing :: VSS Configuration On 6513 Switches

Mar 10, 2013

My question is regarding VSS configuration on Cisco  6513 switches. My understanding is that the hardware and software  configuration on the devices must be exactly the same for the VSS to  function correctly. Do the Bootstrap versions also have to be identical?
 
The production switch is running Bootstrap Version 12.2(17r)SX5, while the new switch is running Bootstrap Version 12.2(17r)SX7.

For some reason i cant undo/delete the AAA commands in order to point to my radius server.  Below was done via console: [code]

I disabled my telemetry port on the Cisco 6513 as a precaution.  The IOS im using is "s72033-advipservicesk9_wan-mz.122-33.SXI5.bin".how to remove the AAA authentication statement.  Hope its not intrusive cause i have a customer on the box.

Cisco Switching/Routing :: 6500 IP DHCP Snooping Over L3 Links

Apr 9, 2012

I am working in a environment that is classed as collapssed Layer 3 environment.  We have a core 6500 with routed links to 3560's which are access switches.
 
We have layer 3 vlans on the access switches, one for data one for voice.On the layer 3 vlans we have ip helper addresses that are used for DHCP.  The DHCP servers are located on the 6500.
 
I recently had a incident where someone plugged a netgear router into a desk point because they thought they could use it for a switch.  This router then started to dish out IP addresses to people in the morning for those who came in and docked their laptops.  99% of people weren't affected because they have desktop PC's are their leases hadn't expired.
 
Now we have bpduguard, bpdufilter to prevent people from plugging in switches that send out BPDU's.  However this doesn't prevent the above senario where someone plugs a router or a 'dumb' switch that doesn't send BPDU's.Because of the above senario I started looking at DHCP Snooping, but I am unsure on a couple of things.
 
With the topology of our network I understand that I don't need to configure IP DHCP Snooping Trust on the L3 uplinks to our core switch.  From what I understand I just need to enable IP DHCP Snooping globaly and then on the VLAN's on the access switch (because of the L3 topology VLAN's are local to the access switches).  Only if I had L2 uplinks to the core would I need to configure IP DHCP Snooping Trust on the trunk links.

Cisco Switching/Routing :: 6513 Span Session Limit?

Jul 12, 2012

I have a need to capture some traffic but my core 6513's are already using the limit of 2 span sessions. I can't edit any of the sessions either because I want to source traffic from vlans and you can only do one or the other. Is using a VACL with 'switchport capture' on the destination interface an option ? E.g. I want to source traffic from vlan 10,20,30,40 and send the all to interface Gi10/10 ? Is there any caveats ? I dont need to be too granular with the ACL's but just capture all traffic in those vlans.
