We have a pair of N7K distribution switches connected to a pair of N7K Aggregation switches.We run vPC on both pairs of n7k's.
-n7k-d1 has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC1)
-n7k-d2 also has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC2)
My problem is that Spanning-Tree is blocking PC2 and all traffic from n7k-d2 is traversing the Peer-Link before reaching the Aggregation layer. Is this the best design for connecting two pairs of n7k's with vPC or if a better design would be to connect all 4 links into the same Port-Channel and vPC?
I am currently working on a project which requires extending a VLAN over WAN. The equipment I currently possess are:
-2 CISCO 1720 Series Routers (1 Serial & 1 10/100 Ethernet per router)
-2 Paradyne DSL Modems (1 Serial & 1 RJ-11 per modem)
The two sites are about about 1 KM apart.Trunking between the two sites is not possible since:
- Maximum available length of CAT 5, 5e and 6 are 100m.
- Laying a Fiber Optic cable of any kind is not possible since the terrain is extremely rough and would not allow it. Also, there is no existing infrastructure to allow re-using of old Fiber Optic Cables.
- Using a Microwave Transmitter & Receiver did not work. Atmosphere is too humid and too dusty to allow it. A minor success was achieved but only limited to small ICMP packet exchange. Data transfer failed immediately.
I am well aware which routing protocols are used to achieve trunking and inter-VLAN routing. Also, I am also aware that this question might not have an answer because a router would BY DEFAULT not forward any packet to the WAN whose destination address is currently connected to its LAN. It would either drop the packet or just won't pay any attention to it.
For a simple 4x sites design for backup consolidation (3x sites connected to one central site), does the design in the attached JPEG make sense and is the configuration achievable using the specified parts?
Brief Explanation:
- Each site is to have servers with 2x 10Gb/s Ethernet (both teamed/bonded/etc) and one NIC on each of the 2x switches in the site (if possible). Each site will also have 2x Cisco Nexus 5596UP Switch (though the P version may be used instead of the UP).
- Two of the sites are within 10KM of the central site
- The last site is about 35KM from the central site
- It is required to have a minimum bandwidth of 10Gb/s between any site and the central site
- I have specified 10Gb/s LW SFP+ and 10Gb/s LW SFP+ (for the 2x 10KM and 1x 35KM sites)
- are there any special licenses needed?
- as asked before, can such a "simple" design work as-is?
- what sort of single-mode fiber would fit the bill (especially for the 40KM link) - 9nm?
We are running 4x n5k and started with the vPC feature. So my question is, if i can connect a vpc-pair to another vpc-pair?In the cisco docs i can find examples for connecting a vpc-pair to a single switch, or server (with and without fex)But there is nothing about how to connect 4 n5k via vPC feature.
View 10 Replies View RelatedNexus infrastructure is pair of N7K switches, with dual homed 5K/2K devices connected, links use vPC. They want to extend vlan's from the 5K/2K side across a L2 path into another DC, this path is only connected into one of the N7K switches, call this 7K switch A.I'm concerned that packets from the 5K/2K side back to the remote DC could get dropped due to the vPC loop dectection process. If a packet from the 5K/2K side traverses the path into the same N7K (7K switch A) as the L2 extension, I dont see a problem. But, if the etherchannel load balance in the 5K sends traffic to the packet to N7K B, in order to get to the L2 path extension to the remote DC the packet gets forwarded across the vPC. My understanding is that this packet will get dropped by N7K A as its local L2 path to the remote DC is up, is this the case?I see a solution is to plug the L2 path into a 2K, but before I suggest this is my understanding of the loop detection process correct?
View 1 Replies View RelatedI have a design hurdle that I cannot seem to cross. I have two sites and I need the same VLAN to span both sites. I have accomplished this using L2TP but my issue is that I can no longer assign a gateway for this VLAN on the router. The 2 routers are 2821's and are connected with a dedicated fiber run.
Ant recommendation for how this could be accomplished? It would be great if I could have the same gateway at both sites by leveraging some sort of bridged interface (BVI so I've heard) but I am at a loss as to where I should start with this. Also, this is not the only VLAN that needs to traverse the link.
I have two separate companys both with staff at two locations and thier own networks connected with a wireless antenna which provides a high speed LAN connection between offices. I only have a single path through this antenna bridge. I have an SG200-08 switch at each end. What I am attempting to do is utlise the switches to take the two subnets at one office, combine them to one for transfer through the antenna bridge, and then resolve them into the two separate networks again at the other end.
View 1 Replies View RelatedWe have 20+ VLANs on our main network, we have an offsite connected by metro GIG fiber ethernet. Right now, we have a layer 2 connection to there with the core at the main site as the gateway. We have had problems occationaly with the metro ethernet's spanning tree which then we would see our own network and cause an outage, not only for the offsite, but since the VLAN would see itself (not on our equipment but the metro ethernet carrier's) it would effect the main network as well.
What I was going to do to resolve this was change the connection to a routed network, however I need to still send some VLANs over the routed network (there are some applications that require to be on the same subnet as the server). Is there a way to Map the Vlan 10, and 11 at the main site to a vlan 10, and 11 at the remote site using a routed network? I noticed there is something about bridging, would I bridge the VLAN accross the routed MAN connection? Then would I bridge back the other way as well?
Main site has a 6506E
and offsite has a 3750E
We have HSRP between NexusA and NexusB with access layer switches connecting to the core using VPC, We are trying to setup a VAM server Voice recording for Siemens phones. We need to span all voice vlan and point it to the VAM server the VAM server connects to a 3750 Stack considering the amount of traffic multiple span session can generate I plan to move the server to the Nexus directly and run a Local Span Session.
1- As we have two Nexus running HSRP and VAM server only connects physically to one NexusA (I can run local span on that nexusA) the Second NexusB is not directly connected to the VAM server I plan to run ERSPAN so if this is the best design and which path will the span traffic take from Nexus B to NexusA will it go through the access layer switches depending on the vlans allowed on the uplinks or will it go through the 20 Gig uplink between the two Nexus allowing all vlans (VPN peer links) ? WE have approximately 10 voice vlans, Do we an example config for ERSPAN session where the source are vlans (As I am for fimilliar with RSPAN) ?
My Data Center has one single core switch where is connected several servers, one port is the link to the router wan and other port is the link to the FW, my boss wants to install 2 nexus in order to replace the single switch. All my network has only one address, for example 192.168.10.0/24 if I connect two nexus 7010 in VPC and Domain, each nexus is going to has 2 modules with 48 port 10/100/1000 rj45 and i wan to connect servers directly to each nexus, with this figure i'm going to have a group of servers connected in two different nexus, Do they can have the same network 192.168.10.0/24 considering that the nexus are in the same vdc and vlan and have only one gateway for both groups? If the answer is positive, which nexus would be the gate way for that address, the primary or secondary? Or i must have a different address for both group of servers, i mean for example 192.168.10.0/24 and 192.168.12.0/24?thus each nexus would be the gateway for that new address?
To have two nexus connected by VPC in a Domain mean that one computer connected to one nexus can share the same address or vlan with other computer connected to the other nexus????
I currently have two Nexus 5548UP switches in my environment running the latest code (n5000-uk9.5.1.3.N1.1a.bin). Both of these switches are connected via a VPC Peer Link (two ports on each switch in an Ether Channel) and a VPC-Keep Alive Link (a dedicated port). Hosts connect to each switch via a VPC for both IPV4 and FCOE.
As of right now, everything works. I currently have a stack of two 3750 switches that each Nexus is connected to. This stack is doing all the Intra-VLAN Layer 3 Routing for the Nexus Switches. However, I plan to get rid of the 3750s, and move the Layer 3 Routing the Nexus 5548's, so the backplane is 10 Gig instead of 1 Gig.. I have the Layer 3 Daughter Card installed in both switches, as well as the LAN_BASE license.
So, at the moment, I am trying to find the best way to accomplish Layer 3 Routing on these two switches. Since the Nexus switches are not stacked, and the FCOE portion of HA is taking care of by the Multipathing agent on each host, I believe am just concerned with providing Intra-VLAN routing in an HA build where if one switch goes down, VLANs still route through the other switch.
Again, since the Nexus switches are not stacked, I am guessing the best way to handle this is with HSRP, but my experience with that has always been with routers that have a switch in the middle. Can I make HSRP work without having a switch between the Nexus switches? Can I track the VPC peer link, or how do I do it? I guess I am looking for a sample config.
Let's pretend I had two VLANs:
VLAN 20:
10.20.20.254 - GW and 10.20.20.0/24
VLAN 40
10.40.40.254 - GW and 10.40.40.0/24
And I wanted the Nexus switches to route these VLANs regardless of which switch was up / down..
There are two Cisco 4900M L3 switches and two Cisco 2960 L2 switches. I need to configure the two L3 switches to operate as a redundant pair, as the servers connecting to them are connecting using bonded interfaces, which can only have one default gateway. So these two L3 switches need to have the same Vlan interface 1, 2 and 3 IP's set onto them.How are the two L3 switches made aware of each other? via a normal trunk? Is there some special configration for configuring a mated/redundant pair of switches? or are they both just configured as though they were the same switch, but linked?

Essentially, we're moving away from a 3750 stack in the data center and the 5548s are the replacement. We'd want to limit the vlans to the specific server network vlans. Our current setup is a port channel between the 3750 and each of the 2 6509s for redundancy.

View 1 Replies View RelatedThe school I work at upgraded to Cisco Catalyst 2960-S switches, all connected to each other via fiber. I am seeing a problem with one such connection. Cisco Network Assistant showed a "4-Warning" regarding the fiber link port: port was disabled because it was fluctuating between up and down too rapidly. Possible hardware problem, resolve and re-enable. (I'm paraphasing the message...it was 'acknowledged', and I can't bring it back up.)
This message was only showing on our "SV-Copy-Rm" switch's port 49. The other end, on "SV-Maint-Rm" port 49 showed a normal green link status.
Using Internet Explorer, I logged onto SV-Copy-Rm switch's Device Manager, and I first tried disabling/re-enabling port 49 on SV-Copy-Rm. It came back up blinking yellow and showing "port has bad link" when I cursor hovered over port 49. This continued for a few minutes, followed by port 49 being disabled again.
The current thing I'm trying is swapping the connection on both ends to a spare pair of fibers. I'm pretty certain I've swapped to the same pair on both ends, however, now neither switch shows an active link. I've disabled/enabled the ports on both ends, but still no link.
Question: How do I re-establish the above link? (The active connection has 'fallen back' to the designated ethernet Cat 5e connection and is currently running with that connection.)
I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.

A friend of mine runs a small hotel, and would like to enable Wi-Fi in the guest rooms. (One thing to know is the hotel is an old farm house, the walls of which are made of clay/mud/brick/cow poo/thatch etc etc) url...The pink area is a rough guide to the current Wi-Fi coverage. This is broadcast from a 3 antenna Wi-Fi transmitter. (Mostly happy with it's performance.)The transmitter is attached, via an ethernet, to a Powerline adaptor (Blue dot).The other end of the Powerline system is in an office, above the kitchens (Red dot). This is attached via ethernet to the main router.The Blue area's are the guest rooms. This is where he want's to supply a signal to.
1) Buy 6 or so powerline adaptors, that have built-in WiFi, and sign them out on a requested basis. Something like this: ZyXEL WRE2205 Powerline Wireless-N300 Range Extender | Ebuyer.com
2) Buy 3 or 4 basic Powerline adaptors, connect via ethernet to 3 or 4 dedicated transmitters. Because of the risk of theft, all this would be wired up in the loft space, out of sight. Plug extensions would have to be wired up into the loft areas for the Powerlines to plug in to.
3) Dispense using the Powerline network completely. Run an ethernet from the office to room 5/6, then connect up to 3 or 4 dedicated transmitters set up in loft areas.
