[c-nsp] ASR9001 doesn't send log messages

[Jordi Magrané Roig]

Dear colleagues,

I have an ASR9001-S with IOS XR 5.1.3. I have configured the router to send the log messages to a syslog server with the following configuration:

logging trap debugging
logging buffered debugging
logging 10.2.32.254 vrf MGMT severity debugging
logging source-interface Lo20 vrf MGMT

interface Loopback20
 description Mgmt in-band
 vrf MGMT
 ipv4 address 10.2.33.129 255.255.255.255

The router has ping with the syslog server and the server firewall permit the packets. I have put a tcpdump sniffing packets but I don't see any syslog packet.

Are there missing commands that I have to configure?

Is it a bug?


I have the same problem with the configuration backup. I have configured:

configuration commit auto-save filename tftp://10.2.32.254/config.cfg
tftp client vrf MGMT source-interface Loopback20


Best regards,
Jordi
