I have a stack of 3750's running IOS 12.2(25). "IP forward-protocal" command is configured, but the IP helper command is just not an option to put on an interface. Any have any idea of why that could be?
View 2 RepliesI am trouble shooting a SF 200-48P and I am a bit lost without a CLI not used to the GUI. What I need to know is how to add the IP address helper command to the switch?I have a number of IP phones which are not getting an IP address from DHCP (PCs which are diasy chained off the phones are all working correctly). On the higher end switches I would have added the IP address helper command to the VLAN and that would have sorted it. How to do this on the small business switch.

I would like to use the ip address-helper feature of my 3560 switch to point 10.1.0.0/24 to my Windows DHCP Server on 10.0.0.0/24 and I am unsure how to go about doing this.

dhcp requests are not making it to the dhcp server SAME VRF (ip helper-addres is not doing anything.....)extended vrf traceroutes on udp 67 sourced from vlan2 are fine
I am expecting udp unicast packets on port 67 "giaddr" relay packets on the DHCP server generated and sourced by the relay on Vlan1
eg. Mar 1 01:59:06.731: DHCPD: setting giaddr to 10.1.1.1
This exact setup works in our preprod environment with the same code.Only difference is we run Distributed etherchannel on the 6500's where this doesnt work.
Wireshark on the client I can see the requests being sent Going to check it with debug ip dhcp server to check the relay logs out of production hours.
I have seen so many people say it IS and ISN'T supported on this version of the code.e.g. [URL]
I am aware the helper-adddress should inherit the vrf of the interface ip helper-address vrf command is not supported.The fact it works in the PP environment.... could this be due to the Distributed EtherChanel difference? or just some bug....
My actual Scenario
1 x 4500 and 1 x 3560?They are gateways of 8 Vlans?They are doing HSRP in each of those Vlans?The 4500 is the Active?There is a DHCP Pool for each of those Vlans on both gateways using "ip dhcp excluded-address" I ensured that the range of provided ips by each DHCP server will not be overlapped Obs.: Reducing the lease time, I ended with the calls bringing related problems.
OK, every thing is blue, every thing is fine.But the network diagram is realy complex(41 switchs, 89 uplinks), and depending of how is the network flow, one or other server answer first or latter.
For many reasons I would like that the secondary DHCP server would answer only if the primary DHCP server goes down.To me, the bigger reason is that DHCP database would be only in one DHCP server.But there is other reasons.
I passed by many frustrated solutions:Try to force a delay on the answer on one of the servers. - Impossible.Try to disable DHCP server, and, using EEM, enable it only if router became active in HSRP. - I couldn't do It.
What I'm thinking now is use the HSRP resource to resolve it.On both routers I would put a "ip helper-address" pointing to an Virtual_HSRP_IP.And depending on which router is the active, him will answer the request.
My first doubt is:Would it work?The second doubt is:Could I use the same Virtual_HSRP_IP that exists on that Vlan(see example 1),or I would need to point it to a Virtual_HSRP_IP in a different Vlan(see example 2)?

I am trying to run the following commands on a 2801 router, but the commands are missing:
mls qos
mls qos map cos-dscp 0 8 16 40 32 46 48 56
The only QoS command i have in global config is (no MLS qos) :
REMOTE-ROUTER1(config)#qos ?
restore-show-output Restore old show output
shape-timer Set the HQF shape timer interval
The router is running IOS:
System image file is "flash:c2801-ipbasek9-mz.151-4.M5.bin"
Am i just running the incorrect IOS or am i missing somehting, i need to change the QoS Map for my Nortel VoIP. The VoIP phones connect to a 3750 PoE which used to conenct to a 2651XM to route VoIP and data traffic over the same copper pairs (WAN link to hub site) hence the need for a Service policy but being Nortel phones, require changing the cos-dscp map. the 2801 is going to replace the 2651XM using a new HWIC.
My 3550 is always 2 characters short on the command line. So my global configuration mode will look like this:Switch3550(config Say I wanted to enabled ftp, it would look like:Switch3550(config)# ftp enab.
View 2 Replies View RelatedI've finally got my 3560 switch IPv6 capable (IP Services IOS), but I've stumbled upon something strange: I can configure a tunnel interface, but I can't put the tunnel in ipv6ip mode. The command is missing. I can choose GRE, IP in IP, and a bunch of other things, but no ipv6ip. I'm a bit desperate here and probably I am going to have to live with it, but just in case? I need the IPv6 tunnel for an uplink to a tunnel broker which only supports this type of tunnel, and I'm surprised this is missing.

I came across an interesting issue and thought I would see if anyone else has encountered it before contacting TAC.I have two Cisco Catalyst WS-4510R-E switches with a single Supervisor V module in each chassis. Both Sup cards are now running 12.2(54) SG1; ipbasek9 firmware; yes, I plan to move both switches to 15 code but that's another story. Anyways, prior to the upgrade the one switch was running 12.2 (33) code; I suspect the code was never upgraded; running ipbase non - K9 code. The other switch was running 12.2(44) with K9 prior to upgrade to 12.2(54).

All SCEA would need from your local PD is an affidavit request / warrant (whatever their specific agency prefers to use or call them) asking SCEA to acquire said information."However, I also realize that I can find my MAC address through command prompt on my windows.
