SNTP on CSS11000

Hello All,

I've read throught the other posts about SNTP and still can't get it working on some of my CSS boxes. I can ping the time server but the sys.log shows the following error message:

JUN 10 15:49:52 5/1 54 SNTP-7: Sending SNTP packet to X.X.195.10 , port 123

JUN 10 15:49:52 5/1 55 SNTP-7: Ipv4SntpSendRequest: forwEntry non-exist for X.X.195.10

(IP addresses changed to protect the network)

Can anyone help me out with what the log messages mean so I can continue to troubleshoot this?

Re: SNTP on CSS11000

could you tell us what is the software version you are using.

Also, what is the routing table (is there multiple possible routes for the destination - all possible routes - not just the exact match)

Re: SNTP on CSS11000

Thanks for your reply. Here is the info you asked for.

LABCSS1# version

Version: ap0610004 (6.10 Build 4)

Flash (Locked): 4.01 Build 9

Flash (Operational): 6.10 Build 4


Licensed Cmd Set(s): Standard Feature Set

Enhanced Feature Set

Secure Management

LABCSS1# sho ip rou

prefix/length next hop if type proto age metric

------------------ --------------- ---- ------ -------- ---------- ----------- 2 mgmt local -- -- 1020 local local 82783 0 2 mgmt static -- --

X.8.0.0/16 2 mgmt static -- --

X.15.144.0/23 2 mgmt static -- --

Here are the route statements form the config:

ip route 1

ip route 1

ip management route X.8.0.0

ip management route X.15.144.0

ip management route

The SNTP traffic should(?) be using the management route: ip management route X.8.0.0, X.8.0.0/16 2 mgmt static -- --, which according to traceroute it is:

LABCSS1# traceroute X.8.195.10


traceroute to X.8.195.10 from 30 hops max, 40 byte packets

5 TTL: 199 ms 199 ms 199 ms From X.15.145.78

6 TTL: 199 ms 399 ms 199 ms From X.8.195.10

Sorry about the "X" in the routes. Trying to keep a little security on the public addresses.

Again thanks for the help and please ask if you want more info.
