SG300-28 Could not add more than 54 IP address and show "No more IP addresses could be added."

[james.ck.chien]

Hi there,

          I have one problem,I have one SG300-28 28 Port Gigabit Managed Switch,  FW ver as below

switch4219a2# show ver
SW version 1.4.7.6 ( date 07-Dec-2016 time 18:37:03 )
Boot version 1.3.5.06 ( date 21-Jul-2013 time 15:12:10 )
HW version V04

Please check console Log  "Log_L3Switch_IpAddr_Issue.txt" for show ip interface, show running, and show vlan log.

When I try to create the 55th ip address binding of vlan748 (See Ln 445), it show "No more IP addresses could be added."

I can success to create the vlan748 Ip address as soon as I remove vlan747 ip (see Ln453, and Ln456).

So it seem the ip address is limit to max of 54?   

But from the Spec here highlight "http://www.cisco.com/c/en/us/products/collateral/switches/small-business-smart-switches/data_sheet_c78-610061.html", the max IP interface should be 128. Any suggestions?

IPv4 routing

Wirespeed routing of IPv4 packets Up to 512 static routes and up to 128 IP interfaces

Hello,

My name is Rozana and i am an engineer from the SMB team.

I viewed the txt file, and i saw that you already have an IP for VLAN 747.
When you tried to add an IP address for VLAN 478 - the switch accepted that.

You can not add 2nd IP address for one VLAN. That is why you get that error.

The max capacity is 128 VLAN interfaces ( 1 IP address for each VLAN ).
If you experience issues with this, please contact our support line and we will research further.

Regards.

Hi Rozana,

    Thanks for your response, but this is not the case.  

    Actually I do the below test.

Step 1 configure  vlan700~747 with an IP and it work. 

Step 2  add ip to vlan 748 but fail(see log file ln 445),  it shouldnt fail in this case as i only have 54 ip binding.

Step 3 remove vlan 747 ip (ln453 in log)

Step 4  add vlan 748 ip again (ln 456 in log, now it work as i remove one IP in step3)

Step 5 add vlan 747 ip again but fail (ln463 in log)

The case you see is in step 5 where i already remove 747 ip in step 3, so at the moment it should work but fail.

Any suggestion?  Thanks

Best Regards,

James
