Bonjour, Il semble que le site B peut envoyer du trafic vers le site A via le site-to-site VPN. Ce trafic peut arriver au site A et le site A peut l'envoyer au site C via un routage static. Cependant, le problème semble être lié au trafic de retour. Le site C ne sait pas actuellement comment communiquer avec B. On pourrait configurer un routage static dans le site C qui pointe vers le site A. Si cela ne fonctionne pas, les sites Site C et Site A peuvent peut-être partager un protocole de routage dynamique. Le RV320 et TP-LINK prennent tous deux en charge le protocole RIP. Peut-être, si vous souhaitez partager une topologie plus détaillée et un photo de la configuration des sites A, B et C, cela pourrait aider à résoudre les problèmes plus en détail. J'espère que cela vous aide. Cordialement, Eduardo Cruz ... View more

Bonjour, Pouvez-vous publier le résultat de 'dir all' et me faire savoir quels fichiers spécifiques souhaitez-vous déplacer? Je vous remercie, Eduardo Cruz HTTS Enterprise Switching CCIE R/S #60411 ... View more

Bonsoir,   A mon avis, cela ressemble à un problème avec le registre de configuration (config-register) des routeurs.   Pourriez-vous poster une "show ver" de chaque routeur s'il vous plaît?   Je vous remercie, Eduardo HTTS Enterprise Switching CCIE R/S #60411 ... View more

Thank you again, Can you also enable "logging monitor 7" under the switch global configuration mode  please? Kind regards, Eduardo. ... View more

Good day, This could be related to drops or errors in the interfaces. Can you send over the output of command "show interface counters error" please? Hope this helps, Eduardo. ... View more

Good day, If the switch status is up/up when the camera is offline, this does not look like a PoE issue, but rather we must verify if the camera has an IP address or if it is reachable via ping.   Also, verify in the switch side if there is the MAC address of the camera being learned in the switch port properly, as well as verify if there is an ARP entry in the switch acting as default gateway for the camera.  Hope this helps, Eduardo. ...

Good day, Software train 16.2.x is now deferred because some serious issues were found in such.  For your Cat9300 platform, you may want to use either software version from the 16.6.x train. Hope this helps, Eduardo. ... View more

Thank you for this new information, Looking at differences, the Cat2960 switch has monitor logging enabled, whereas the Cat4500 switch has it disabled.   2960 Console logging: disabled Monitor logging: level critical, 0 messages logged, xml disabled, filtering disabled Buffer logging: level debugging, 2949 messages logged, xml disabled, filtering disabled 4500 Console logging: level debugging, 4629 messages logged, xml disabled, filtering disabled Monitor logging: disabled Buffer logging: level debugging, 187 messages logged, xml disabled, filtering disabled Can you enter the following configuration please? Switch# conf t Switch(config)# logging trap 7 Switch(config)# end Switch# wr If it does not work, then we may need to take a packet capture a hop ahead of the Cat4500 (because mgmt port Fa1 has certain limitations), to see if packets are going out.  Another thing that I could think of, is that the service could not just start, and a reload may be required, but I would prefer to try the steps mentioned above before doing so. Hope this helps, Eduardo.       ... View more

Understood, thank you, Could you attach the output of "show log" of both the C2960 and C4500X please?  I would like to see if there is some other option enabled by default in one platform but not the other. Kind regards, Eduardo. ... View more

Good day,  Some platforms have logging disabled by default. Could you enter the following and see if it helps?   Switch(config)# logging on   Also, it looks like the interface that will go out to the server for logging purposes is under a vrf. Could you verify if the server is reachable under such vrf, please? Switch# ping vrf mgmtVrf 10.11.128.122 source Fa1 Switch# ping vrf mgmtVrf 10.11.128.122 source 10.11.175.199 Hope this helps, Eduardo.   ... View more

Hi Ian, Looking over the wording, I agree, it looks like the packet is transparent to the router from an Ethernet standpoint. Kind regards, Eduardo. ... View more

Good day, The issue seems to be a router crash due to a memory allocation failure.    This could be related to a software bug, so one of the things I would suggest is upgrade the router to the latest IOS available. Did the router generate a crash file? Can you share the output of "dir all", please? Hope this helps, Eduardo.     ... View more

Good day, When the F5 LTM performs a failover, I would expect that it sends something called "Gratuitous ARP". This ARP packet is useful to inform other hosts (such as the Cat3750 switch), that the MAC is no longer advertised via the previous "NIC". On the other hand, ideally, the moment the Cat3750 switch receives and processes this gARP packet, it should flush the old entry and learn the new one. This completes a successful failover. My theory is that either the F5 does not send a gARP, or the switch fails to process it. My suggestion is that a packet capture is taken at the F5 to see if such gARP is sent in the first place. You can also do some conditional debugging at the Cat3750 (debug condition interface Gi x/y/z), followed by debug arp to see if such packet is ever received. Alternatively, you may try to reload/upgrade the Cat3750 to see if some bug does not allow the Cat3750 switch the proper processing of gARP packets, although I would prefer to have evidence and not just upgrade. Hope this helps, Eduardo. ... View more

Good day, Maybe someone else could comment, but based off the symptoms provided (e.g. VIP cannot be pinged when Brocade is the Active VRRP device) this looks like a Brocade-specific issue. Is there any evidence that you found that could tell you this is an IE issue? VRRP Active-Master failover seems to work fine so this means the Brocade and IE devices can listen to each other. I would be concerned if somehow, end devices, or switches downstream still believed that the way to reach the VRRP Master switch is still via the IE when it is Standby (not Master anymore), instead of the Brocade (e.g. some old VRRP MAC address still pointing to the wrong interface). You could try to take a packet capture on the incoming interface of the Brocade, to see if the pings are coming in.
