• VLAN function 6248 switch IP address

  We have a nice and simple class C private address space private on 4 x Dell 6248 switches. We are running out of IP addresses. We could change the netmask (add more bits), but who is to reach each node and potentially finding devices that do not work with anything other than 24. We have a lot of old material that we must keep functioning. In addition, we want to limit emissions, since here we have projects that do a lot of UDP broadcasts. If each project in one VLAN, the load on the switches would be less. Hosts on VLANS must get to the common servers well.

  So I did some reading and thought we would use of VLANS, routing and others to have several C class spaces. We turn the material around the office at an alarming rate so I thought that an IP based VLAN would be an excellent solution. I have problems with the documentation and configuration to make it work.

  We have 2 x 2716 Dell and 2 x Dell 2724 switches in the mix as well. They are connected to the 6248 s switches dumb and all seems to work now.

  I created 2 VLAN and reports the following:

  Curetes #show ip interface vlan 2

  State of the Routing Interface... Down
  Primary IP address... 192.168.3.1/255.255.255.0

  I am running firmware V3.3.3.3. I have improved the switches on the weekend of 2.2.0.3 I read that VLAN does work well with this version.

  I can't find in the documentation "Setup Guide" or "CLI_EN.pdf" how to get the "Routing Interface status" that up to.

  My config running is pretty simple:

  ! Current configuration:

  Question (in order of importance):

  What is the best way to go to solve my problem (limit/exhaustion of Ip address space broadcast domain)?

  How to make "Routing Interface Status" on VLAN 2 upward? Do I need it upward?

  How to configure a VLAN to do what I want?

  Thanks in advance.

  Yes, that's my suggestion.

• Reference Dell 6248 find IP address port

  Hi, I use a Dell 6248 switch and I want to spend the vlan of a particular device, but I do not know on which port the device is connected. How can I find this information without having to physically go to the switch.

  I don't know if it's serious or not, but the switch dell isn't the switch doing the routing.

  Hi, I left the company that had this switch in January 2013, so I wasn't able to test the last response before yours, but nothing before that worked.

• Reference Dell 6248: hot swapping and upgrade battery links

  I have a set of switches Dell 6248.  I have a few questions to explore:

  (1) can I add/remove the CX4 cables while the switch is working?  (I guess it's the same rules as a cable normal Ethernet...)

  (2) can I add/remove modules while the switch is working?

  First scenario I'm looking at: extend the stack on a stacked rack.

  I think the process here is, install a switch of spare with stacking module, run off battery cables to the battery, breaking and re-Assembly of the ring, then turn on the switch, confirm the ID stack and connectivity and migrate customers to it.  I can totally hot cables plug the CS4, right?

  Next scenario I'm curious: upgrade of 12G to 48G stack.

  Can I exchange the accumulated 12 GB card and swap the 48G card in when the switch is on, or do I have to turn it off?  Connectors on the 48G card the same?  (CX4..)  Can I / layout 48G and 12G cards in a pile during my upgrade?  Is the maximum length of cable the same (3 m) on a stack of 48G?

  Thank you!

  -danny

  Hey Danny,

  The stackable modules are not hot-swappable. The cables are, but for the modules to detect that it must present when the switch is started. A reboot is also required for stacking on these ports using Ethernet. Yes 48 GB stackable modules also have a 3 meter cable.

• Reference Dell 6248 as default gateway - next hop router

  Hi all

  I guess it's a matter of very basic network design. Good practice / can I use Dell 6248 layer 3 switch as the gateway / next hop router, even if the correct entry door is directly connected to the same subnet / vlan?

  The problem is that we are making changes to our network, and have several routers on the edge of our network configured static routes so they can achieve our other subnets, local and remote. These static routes will need to be changed when we move from one circuit to another, but some border routers are managed provider, and it is inconvenient to reschedule. Also, sellers will have to do more than once, the road changes if we want to clean our ip addressing scheme after the move. Once the changes are made, the topology of the network likely will not change for a long time, so I would stick with static routing. Given that we can grasp and control the static routes in our Dell 6248, can we just say sellers use our Dell switch as the next hop router when they change their static routes?

  I know that ip redirects could try to "correct" this inefficient configuration, and that could cause problems, at least during the transition phase. On a small network with 10 servers, 100 computers and 80 phones, is it without further consequence of routing for the Dell 6248 layer 3 switch, or is this something configuration you should avoid (for other reasons)? Thanks for your understanding!

  Without seeing a topology, you may be a little difficult to give recommendations. Is the 6248 your switch? It connects to your firewall? All edge switches are like L3 switches that are basically their own broadcast domain? If so, then what you are wanting to do would work. All edge switches have a static route of coverage which directed traffic to the 6248. You then place a static route pointing to the firewall on the 6248.

  If all switches are in L2 and the 6248 mode is the only L3 switch on the network. Then the switches will not need static routes.

• Replace the battery. Reference Dell 6248

  Hello!

  We have a set of three Dell Powerconnect 6248 switches.

  One of the switches must be replaced with the new one (same model).

  the well known "pwcnt_stacking_switches.pdf" document does not say how to replace a member of the battery,

  just how to add additional, or to remove switch a.

  It is said in the documentation for the 3524 powerconnect switches:

  Exchange of stacking of members
  If a member of the stack with the same unit ID replaces an existing UnitID with the same ID of the unit, the
  the previous device configuration is applied to the inserted stack Member

  Even apply to 6248? This approach works?

  How a stand-alone switch can be prepared to be added to the stack as some number of particular unit (excluding implementation stack-port mode battery)?

  is it

  Renumber (conf) #switch

  ?

  Yes, guess I replace unit Number or number 2. (out of three)

  Once I have remove the old unit 2 and insert a new one, the new switch will get UnitID = 4.

  After I using renumber

  switch 4 renumber 2

  He will get all the previously attributed to the old switch 2 port configuration?

• Newbie connection DELL 6248 pile to pile of CISCO 3750

  Hi all

  I need to extend the desktop LAN by connecting a battery of CISCO 3750 existing a new pile of DELL 6248.

  I intend to use the fiber/combo harbour in DELL 6248 to connect to the CISCO uplink port.

  I want to use DELL port 48 but I saw there was 1/g48 and 1/xg48.  From memory, they are mutually exclusive.

  Q1.  That means I'll just set up 1/g48 and do not enter the config of 1/xg48 of the sentence?

  Q2.  To connect together the 2 batteries, devrais I defined just two ports to connect as a trunk port?  I have no experience in doing so.  FOR INFO.  We already use VLAN in piles CISCO and so the new DELL batteries must know about it.

  Any help will be very appreciated!

  Combo ports have a combined input and output of the PHY chip. Only the optical port or RJ-45 port can be used individually, but not at the same time. Any cable is connected will first use the port PHY. If the Ethernet port is used, you will configure with 1/g48, if fiber port is used then set up uses 1 / x 48.

  Yes, you are right, a network connection is what you want between the two battery. Commands on the switch PowerConnect looks like this.

  Console > activate

  Console # config

  Console (config) # interface ethernet 1/g48

  console switchport mode trunk #.

  console # permit trunk switchport vlan add 2,3,4,5

  On the PowerConnect 62xx switches, you must use general mode if you want to allow traffic from management on the switch on the PVID.  If you use the Trunk mode, you will not have the default VLAN on these ports.  The ports will only allow labeled traffic. So if the Trunk mode does not you, then switch to general mode.

  As the pile of Cisco has already VLAN on it, we must ensure to the PowerConnect switch has those same VLAN. Here is an example of creating a VLAN on the PowerConnect switch.

  Console > activate

  Console # config

  Console (config) # vlan database

  VLAN console(config-VLAN) # 2

  output console(config-VLAN) #.

  Console (config) # interface vlan 2

  Console # name Marketing

  Console # end

  Another thing you may perform is place a static route to help the traffic at the back of the battery.

  IP route {network} {mask with joker} {Next Hop-IP}

  Console # config

  Console (config) # ip route 172.16.0.0 255.255.0.0 10.0.0.2

  Console (config) # end

  I hope this info helps,

  Thank you.

• Changes in the incoming packets to address SG300 inter - VLAN routing and MAC

  Hello

  I SG300-20 operates in Layer 3 mode

  Vlan1 is not used

  Gateway Internet is VLAN211

  Customers are in other VLANs

  Switch is the default gateway for clients and itself has internet gateway as default route.

  The switch MAC address is XX:XX:XX:XX:XX:63

  When the client sends traffic destined for Internet MAC address in outgoing packets is XX:XX:XX:XX:XX:63

  But in incoming packets the source MAC address is XX:XX:XX:XX:XX:69

  Why change? And how can I set the switch to use MAC XX:XX:XX:XX:XX:63 address?

  I finished the event and found that it does not change as expected. When you use the switch to Layer 3, routing, with or without him as your default gateway, it will happen.

  I tested two different VLAN in two different ways, and every time that I ping via the switch to a different subnet, the MAC source on the return package was different on the last two. This is due to the fact that the return traffic through a different interface on the switch.

  Currently, there is no option to change this.

• My PowerConnect 6248 switch loses its settings when disconnected from the power

  Hello

  I'll put up a PowerConnect 6248 switch on my local network through Web interface (I can't use serial to do).

  I put the IP, login, password, a LAG, SNTP server address, etc.

  It works fine until I unplugged the power cord to the switch to simulate a power outage. When I plugged in the power cord, the switch will reboot by displaying its default settings and I release all of mine.

  Y at - it a specific command, I missed to save all my settings in the switch?

  Thank you for your help.

  Pascal.

  The switch has two separate configuration locations, a running configuration and startup configuration. This allows you to change configuration and test running before engaging them in the startup configuration. Once you have the running configuration, how you want it, you need to run the # copy running-config startup-config command, or just copy # run start.

• Blocking MAC address on PowerConnect 6248 switch

  Hello

  I have a PowerConnect 6248 switch where we want to block a specific MAC address from the rest of the network.

  I created a list of MAC access with the following commands:

  Console (config) #mac access-list extended BLOCK
  Console (config-mac-access-list) #deny 001D.09D4.B08E ffff.ffff.ffff all

  Console (config-mac-access-list) #permit a whole

  I then apply it to all interfaces:

  console (config) #mac group-access BLOCK

  What ends by goes, is that all hosts connected to the switch are blocked when my rule should only be blocking the host with mac address 001D.09D4.B08E.

  What I am doing wrong?

  Thank you!

  Have you tried changing your statement to:

  Console (config-mac-access-list) #deny 001D.09D4.B08E 0000.0000.0000 everything
