Recently a new W2K3 file server was deployed on a LAN that I manage. Since the deployment, users on the LAN have complained of poor performance when using services on the new server. I mirrored the port and discovered that the new server was sending a massive number of ARP requests...

Hi all.... I'm a Cisco guy trying to work with a 3Com switch 4400. First off, let me define what I mean by the term "trunk". Cisco refers to trunks as lines that carry multiple VLANs. 3Com seems to refer to trunks as port aggregation groups. I am using the Cisco definition of a single...

Does anyone know if the 3Com "Port Trunk" link aggregation is compatible with Generic Link Aggregation on NICs with the Broadcom chipset? If you can't answer this, can you tell me if 3Com's "Port Trunk" link aggregation is compatible with Cisco's EtherChannel link aggregation? Thanks

Okay, I've been away from NNM for a few years. I have a question about the values presented by the data collector. Specifically, IfInOctets and IfOutOctets. I fired up the data collector to collect those two variables from a Cisco switch, exported them, then used ovcolqsql to extract them...

Where is the capture file format (.cap) documented? Since there doesn't seem to be a good solution for decoding TNS/SQL frames on non-standard ports, I want to alter the TCP port numbers in the raw capture file to force the sniffer to decode these packets. Network Associates/General: A nice...

Ok, I'm sure I'm not the first one to have this problem. Anyone have an easy way to decode TNS/SQL packets? The problem is that the sniffer (4.3.5) has the decode built in, but Oracle uses dynamic ports. I don't know all the details of the TNS protocol, but what I see is this: 1. Client...

Okay, without going into too much detail, I have a Cat6500 (CatOS 8.1) w/MSFC2. I have a VLAN (vlan 60) defined that I will be migrating users to, and a corresponding VLAN interface defined on the MSFC that will be the default gateway for the new VLAN. The VLAN (VLAN 5) that I will be...

I have a situation where I am replacing the network hardware on a campus. In conjunction with the hardware replacement, the VLAN structure is also changing. What I am doing is using a Cat6500 (CatOS 8.1) with MSFC2 to bridge the old and new network together. The old network has a Cat5500 at a...

Okay, let me bounce this off you guys. I have a campus network consisting of 7 major buildings, and I need to design a backbone for it. All of the buildings are connected by fiber, but it is not a full mesh. If you drew seven squares on a page and connected them all in a circle you would have...

I have a DSS 4.50a. The former net admin at the site took the password with him. Does anyone know how to recover it?

Okay, I've noticed that Cisco has announced end-of-sale for the 3500 XL line in favor of the 3550 line of switches. I can order the 3550s with the enhanced image (routing capability) or the standard image (no routing). These switches are access-layer switches (at least in my network). I can't...

Anyone with a CatOS background made the switch to the native IOS software? I am replacing an all Cat5500 network with a Cat6000 core switch and Cat3500 clusters at the edges. I ordered the 6000 with CatOS but it arrived with native IOS instead. I was going to download the CatOS but now I'm...

Hi, Anyone doing remote control of DSPro (4.1) agents? I'm talking about PC anywhere or a similar product. I want to install something like MS netmeeting but I want to be sure that I'm not going to cause any conflicts with the agent. I read in the NAI knowledge base that VNC (freeware remote...
