dhcp packets not visible in 6509 [7:70898]
Hi *, am fairly new to cisco products/ commands. have a problem got a WS-X6348-RJ-45 module at slot 3 of 6509. In which am unable to get DHCP broadcast /address from the main dhcp server. configured all the ports to respective vlan-x and at the routing module in a core switch (6509 with msfc) I hv given the ip helperaddress for this vlan. rest of the catalyst 4006 switch fetches dhcp frm this scope. Below is the module capabilities: Type 10/100BaseTX Speedauto,10,100 Duplex half,full Trunk encap type 802.1Q,ISL Trunk mode on,off,desirable,auto,nonegotiate Channel yes Broadcast suppressionpercentage(0-100) Flow control receive-(off,on),send-(off) Security yes Dot1xyes Membership static,dynamic Fast start yes QOS scheduling rx-(1q4t),tx-(2q2t) CoS rewrite yes ToS rewrite DSCP UDLD yes Inline power no AuxiliaryVlan1..1000,1025..4094,untagged,dot1p,none SPAN source,destination COPS port group 3/1-48 Link debounce timer yes Module configuration: set vlan 68 3/1-48 set port auxiliaryvlan 3/1-48 none set port qos 3/1-48 trust-ext untrusted set port qos 3/1-48 cos-ext 0 set port enable 3/1-48 set port speed 3/1-48 auto set port trap 3/1-48 enable set port name 3/1-48 set port dot1x 3/1-48 port-control force-autho set port dot1x 3/1-48 multiple-host disable set port dot1x 3/1-48 re-authentication disabl set port security 3/1-48 disable age 0 maximum set port broadcast 3/1-48 100.00% set port membership 3/1-48 static set port protocol 3/1-48 ip on set port protocol 3/1-48 ipx auto set port protocol 3/1-48 group auto set port flowcontrol3/1-48 send off set port flowcontrol3/1-48 receive off set cdp enable 3/1-48 set udld disable 3/1-48 set udld aggressive-mode disable 3/1-48 Cat-OS version: cat6000-sup.6-3-9.bin Can you guide me, anything I am missing out.

RES: dhcp packets not visible in 6509 [7:70898]
Did you enable spannint-tree portfast ? I'd use set port host instead , which includes STP portfast, aomong other things . . . > _ > Henrique Issamu Terada, CCIE # 7460 > IT Support - Open Network > CPM S.A. - Tecnologia criando valor > Tel.: 55 11 4196-0710 > Fax: 55 11 4196-0900 > [EMAIL PROTECTED] > www.cpm.com.br > -- > --- > Esta mensagem pode conter informagco confidencial e/ou privilegiada.

Re: dhcp packets not visible in 6509 [7:70898]
you need to enable portfast. Read about portfast. Set spantree portfast enable ( I think this is the syntax I don't have a 6509 in front of me now.)

Re: dhcp packets not visible in 6509 [7:70898]
Vik, There could be any number of reasons that DHCP isn't working. The client may not be requesting DHCP, the switch may not have portfast enabled, a router not having an IP helper address, DHCP server offline, DHCP server without a scope for the VLAN, and so on. Perform a packet trace from the DHCP client and if necessary on the DHCP server (using SPAN). You will be able to determine the problem by identifying which packets are present in the capture and which are not. For example, you may find that the client sends a DHCP discovery packet but does not receive an offer packet from the DHCP server. If you see the same behavior on the server port (discovery, no offer) then it's possible that: - The DHCP server isn't operational or the service/daemon isn't running - The DHCP server doesn't have a scope defined for that VLAN - The DHCP server has run out of IP addresses for that VLAN On the other hand, if you the capture shows a discovery packet is sent by the client but the packet is never seen by the DHCP server it's much more likely that you have a missing (or incorrect) IP helper address. Once you perform the packet capture(s) you will probably need no further help. If you do, the information obtained from the capture would be enough for the group to point you in the right direction. - Tom Vik Vikky wrote: > Hi *, > > am fairly new to cisco products/ commands. > > have a problem > got a WS-X6348-RJ-45 module at slot 3 of 6509.
