ip address dhcp command not available on C3550

[alabarba82]

Hi,

I'm trying to configure my C3550 with fast ethernet port 0/48 assigned to vlan 2 in static access mode and SVI vlan 2 configured as dhcp client.

But I see command ip address dhcp is not available on interface vlan 2:

Cat3550(config-if)#ip ad

Cat3550(config-if)#ip address ?

  A.B.C.D  IP address

Cat3550(config-if)#ip address  

Could it be a problem related to the version running on the equipment (see below the output of sh version command not sure of what

EA1 stands for)?

I read here http://www.cisco.com/en/US/docs/ios/12_3t/ip_addr/command/reference/ip1_i1gt.html#wp1164194

that this command was introduced in version 12.1(2)T

If it is a version problem is there any possibility to download upgraded version for free?

Thanks!

Antonio

Hello Antonio,

generally speaking yes the IOS version really counts for the feature supported.

in your case C3550 is now an old platform that might be upgraded up to 12.2(44)SE as we can see

http://www.cisco.com/en/US/products/hw/switches/ps646/prod_command_reference_list.html

the dhcp option is not present even in last command reference see

http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.2_44_se/command/reference/cli1.html#wpmkr1861935

to upgrade you need a regular contract

So it looks like it is not supported on C3550

Hope to help

Giuseppe

Hi Antonio,

ip address dhcp is interface config command as shown below

3550SMIA(config)#int fa0/17
3550SMIA(config-if)#ip add
3550SMIA(config-if)#ip address d?
dhcp

3550SMIA(config-if)#ip address dhcp ?
  client-id  Specify client-id to use
  hostname   Specify value for hostname option
 

Its not available under global config.

Thanks

Thank you guys!

so it really seems I could solve the issue by upgrading my IOS version to Version 12.2(44)SE6.

Anyway it's really strange, as me too I have just verified, this command to not be inserted in the command reference.

Beside this I have purchased this switch on ebay and I have regular invoice, Giuseppe when you say "I should have a regular contract", do you mean a sort of payment technical support contract?

Thanks

[Reza Sharifi]

Antonio,

Cisco does not offer warranty and contract services for equipment purchased on ebay or any other auction site.  In addition to service contract, you need a CCO account to download the IOS.

Hi Reza,

excuse me but I never had a chance to deal with Cisco software before now, so I'm pretty ignorant about this.

I logged with my cisco credentials that I received when I obtained CCNA certification and I tried to visit http://www.cisco.com/cisco/software/navigator.html section, I followed all the steps and I finally was able to download the image

Release:12.2.44-SE6

Filename: c3550-ipbasek9-mz.122-44.SE6.bin , Feature set: IP BASE

for Cisco Catalyst 3550 48 SMI Switch

I didn't proceed with the download as I'm not sure if I can download it as I was asked to agree on the following points:

1.         That you shall be bound by Cisco's End User Software License Agreement  posted at the above URL regarding your use of any Cisco software you download from this web site;

2.         That you are only entitled to download Cisco software for the Cisco  hardware chassis or device or the particular application software or  signature file for which you have paid the applicable software license  fees;

3.         That you must purchase a Cisco Operating system Software feature set  upgrade license if the feature set you intend to download is not  included in your initial license;

4.         That you have a current and valid service contract that covers either           the specific Cisco hardware chassis or device for which you are  downloading software and/or the software image or subscription file update (e.g., For Intrusion Detection System) that you are  downloading;

5.         That Cisco reserves the right to: (a) charge you for, and you agree to pay for, software /signature file downloads to which you are not  entitled, and (b) immediately suspend or terminate your access to this web site if you Download software to which you are not so entitled.

I initially agreed with the points above only to see if I was allowed to download the image then I verified i was allowed and didn't proceed with the download.

Now I'm pretty confused about how getting updates and software download works.

Can you please help me to understand better how this process works?

Thanks!

Antonio
