PowerConnect 5448, how to restrict DHCP BOOTREPLY messages to a specific LAN port?

In order to counter the effect of the DHCP server that is not allowed on my Ethernet network. I need to restrict DHCP BOOTREPLY messages on a specific LAN port on which the authorized DHCP server resides.

I tried to read the section "Configuration DHCP Snooping" of the 54xx User Guide, but does not get a clear idea. This description in the user guide seems rough and intuitive for me to understand.

'Trusted Interface Définition' help? I think I need feature 'port of trust '. I hope only trust ports 5448 can receive DHCP BOOTREPLY packages, while BOOTREPLY arriving in untrusted ports is rejected.

Daniel finally understand the missing link after an exchange of emails with me.

I have to add

Console (config) # ip dhcp snooping vlan 1

to finally make it work - even if I don't yet use the VLAN.

See you soon.

  • PowerConnect 5448, how all the trunk of physical ports and allow all the VLAN tags to pass transparently

    I would like to achieve such a goal, do all acts of switch ports 5448 as 'trunk', that is, just as an entry-level switch. Yes, I want all the tags VLAN through seamlessly.

    Let me explain more clearly. If

    • With MAC1 PC1 is connected to switch port 1 (port 1) in short, PC2 with MAC2 is connected to port 2.
    • PC1 sends a packet with vlanid = 30 ethernet VLAN tag,.

    I want the ethernet packet must be SENT to port 2 without modification, i.e. 2 PC will receive the package with exactly the same byte packets that PC1 sends.

    Currently, I want to configure all ports from the switch to act like this, but how to do this? Can someone tell me the more concise CLI commands to achieve? Alternatively, it is possible via the web interface?

    I must again complain the poor manual, which talks about this concept and this notion over and over again (both of ambiguous statements that the author of manual does not), BUT doesn't explain them not at the level of the content of the packages, so I'm totally at a loss.

    I tried the web interface. Simply together port 1 and 2 for access mode or general mode does not work.

    Please help me. Thank you in advance.

    Thank you, Josh, you begin to point me in the right direction.

    Now, I know just affecting a Trunk port, or general mode is NOT sufficient.  I have to give what kind of package VLAN (i.e. what VLAN ID) are allowed to pass through.

    To do this assignment, I have to take 2 steps. say first of all, the database "vlan" to recognize a VLAN ID in the world, then say that some specific port is allowed to pass through with this VLAN ID specific packages.

    Thus, in order to pass packets VLAN with VLAN ID 18-25 no modified (marked packets in packages marked on) g7 to the g8 to port port, I have to do:

    Console # config
    Console (config) # vlan database
    Console(config-VLAN) # vlan 18-25
    Console(config-VLAN) # exit

    Console (config) # interface ethernet g7
    Console # switchport general mode
    Console # switchport General allowed vlan add the tag of 18-25

    and again for the g8. And if I want to 48 ports to act like that, I have to write this kind of order 48 times right? All the shortcuts?

    I would not disturb that, unless block you also all kinds of internet connectivity, ban installs them, access to records system, the bios password, remove completely the usb drivers, block the visibility of the post, disable usb on motherboard, disable uefi, assign admin security locks, network and start of recovery and encrypt hard drives (bitlocker or material) your choice).

    At this time, there are chances that you shouldn't provide a computer at all. Best policy is good data access governance.

  • Change of address IP PowerConnect 5448

    Ive got 2 x Dell PowerConnect 5448 and set an ip address on VLAN1 [I think!], so that I can access the web interface. Im trying to change this ip address, now but cant seem to do this through the web interface, Ive also tried to use CLI but cannot find where it is configured. Ive looked in the settings of VLAN and ip settings in the CLI but cant for the life of change me the ip address. In the web interface, I tried assign another ip to the vlan1 but I get an error message means that you can define only a single ip address per vlan. Anyone know how change the ip address through the web interface or by using the CLI?

    I also want to create a vlan port base to 1-5 on the switch ports. Am I right to assume that by default, all ports on the switch belong to the vlan1 and I would need to create a vlan2 for ports 1 to 5?


  • Need help to configure the VLAN on a powerconnect 5448

    Hello world

    I am currently working on 2 switches PowerConnect 5448 but I'm completely lost in configuring VLAN.

    My bow:

    My needs are:

    -J' have 2 different networks that need to be isolated in different VLANS

    -I want to port 11-14 to use for network backup, all others must be used for the production network.

    -This 2 networks must pass through the port 48 (fiber)

    How can I configure this kind of network on the powerconnect interface (or via telnet)?

    My understood are the following, I have to create 2 different VLAN tag all ports, switch to safe mode all ports of the entitlement each port to the VLAN voted. Am I wrong?

    How the fiber port?

    Thanks in advance for your help on this matter.

    Since your 2 VLAN need not communicate with each other, you should be able to get this working.

    The easiest way to do this would be to have your production on VLAN 1 and VLAN 2 second network.

    Assign an IP address to the switch with the command IP #.

    Assign a default gateway with the # ip default-gateway command.

    Create a VLAN 2:

    Database console (config) # vlan

    Console (config - vlan) # vlan 2

    Set 11-14 ports to access the mode for VLAN 2

    Console # switchport mode access

    Console # switchport access vlan 2

    Set 48 on trunk or general mode ports.

    Console # switchport mode Trunk

    console # permit trunk switchport vlan add 2

    You should get pretty close to a work environment. You may encounter some problem with VLAN 2 contacting 192.168.1.0, maybe just need to put it up and test.

  • Vs LACP LAG between two PowerConnect 5448 s

    Hi all.

    Just got a switch configuration quad for our infrastructure EqualLogic SAN using PowerConnect 5448 s.  One thing I never did before her configuration of aggregation of links.

    If I wanted to set up an aggregate of 4-port connection between two switches, say on ports 1 to 4, and our iSCSI VLANS is 1000, the below will work?

    serial interface ethernet g(1-4)

    channel-group mode 1 on

    interface port-channel 1

    switchport general

    switchport General pvid 1000

    I've seen documentation on how to get the ports-working channels between a 5000 or 6000 switch and a Cisco Catalyst switch, but not just any what docs on how to connect two switches PowerConnect.  The doc of interoperability for Cisco <->Dell seems to want to use LACP on the side of Dell.  I wonder, should I configure and link LACP on the two 5448 aggregate s I have are running?

    Thanks for in advance for any advice or assistance!
