    Hey

    I've been poking at a CCNP study guide and had a couple of questions.

    - The book does not seem to consistently distinguish between 'packet' and 'frame'. That is, they'll be talking about Layer 2 and call the PDU a packet. Is it just colloquial to use 'packet' everywhere, or is this the book being weird?

    - Their definition of CAM (in the appendix) feels extremely off: "A high performance table used to correlate MAC addresses to switch interfaces that they are attached to." Based on the text (and wiki, etc) CAM seems to just be a type of memory, suited for different tasks than RAM. Is it somehow useful (at this stage / in this context) to just focus on how it facilitates forwarding?

    - Where I would expect 'transmitted' or 'sent' (or similar), the book uses 'advertised'. Is this a general colloquialism? Specific to control plane traffic? The book trying to make fletch happen?

    Thanks.

    Frame vs Packet is about what OSI later you are talking about. At Layer 2 (data link) you have a Frame with the MAC addresses. At Layer 3 (network) you have a Packet with the IP addresses. A Frame encapsulates (wraps) a Packet. You cannot have a Packet without a Frame, but you could have a Frame without a Packet.

    A PDU (protocol data unit) can refer to a Frame, Packet (IP), Segment (TCP), or Datagram (UDP). It is just the generic term for any single bundle of information.

    CAM is where the switch port stores it's list of MAC addresses (physical devices) it can see to allow the switch to forward frames out the correct switch port. Its just faster to access than if it were stored in main memory to speed up traffic flow through the switch.

    Transmitted and Sent are the same thing. Refers to anything and everything that leaves a switch port. Advertising means "I know some config/state info and I need to send that info to other devices on the network". So an Advertisement will be Sent/Transmitted, but most things that are Sent/Transmitted are not Advertisements.

    But Cisco are weird in that they tend to use terms in their own way that may not correspond to typical usage, but their tests expect you to know how Cisco uses it, not how anyone else does.

    CAM is basically reverse RAM, it does constant-time searches. It is used for doing lookups like vlan/MAC address -> port or whatever, and referring to that address table as "the CAM" is rather colloquial but people would normally get it. Woo Cisco terminology!

    It is like defining RAM as "where we keep track of all the game objects and their position/state" as a game developer, which may be true and the usage but isn't what "RAM" is or describing how that does it.

    Totally this. Cisco just always does things a little differently. (Or, sometimes, a lot differently.)

    One of the big examples I can think of is how most switch vendors define VLANs in terms of tagged and untagged ports, while Cisco defines it in terms of access and trunk ports. I've been doing this for years and I it still takes mental effort for me to translate from the Cisco VLAN paradigm to the industry-standard VLAN paradigm and vice versa.

    Or how Cisco ASAs use isakmp and ipsec commands for VPN tunnels, while almost everybody else uses phase 1 and phase 2. (IMO, setting up a cross-vendor VPN tunnel where one side is Cisco and the other is not is always a pain in the ass.)

    https://thwack.solarwinds.com/t5/Geek-Speak-Blogs/The-Pros-and-Cons-of-Open-source-Tools/ba-p/478665
    The Cons of Open-source Software
    Security becomes a major issue. Anyone can be hacked. However, the risk is far less when it comes to proprietary software. Due to the nature of open-source software allowing anyone to update the code, the risk of downloading malicious code is much higher. One source referred to using open-source software as “eating from a dirty fork.” When you reach in the drawer for a clean fork, you could be pulling out a dirty utensil. That analogy is right on the money.

    Even in open source, most hackers don't peruse over the source code to find weakness. Some do but most just look up actual published vulnerabilities for versions, just like they do for microsoft's stuff.

    Anyone have a recommendation on a service that can monitor SQL logs automatically and generate reports on suspicious activity? It's being requested on a security audit and I'd like to find something simple that I won't have to spend 50 hours setting up and managing.

    I am basically being told that we need to have a system that can audit the administrator activity in the event someone manages to hack into SQL and steal data.

    Getting people to log, even just for compliance, is often half the battle, unfortunately. Sometimes the only way folks will prioritize the work is under threat of massive regulatory penalty.

    But yeah, if you have it but don't use it that's just stupid. Especially now that most logging solutions also have integrated alerts/reporting.

    I had an unsatisfying conversation with my manager today.

    Me: "I delegated TaskA to Junior Employee and he completely flubbed it. I felt like I gave him very clear instructions and it was a very simple task."
    Boss: "You shouldn't have delegated that to him. I don't see TaskA as being within his role."
    Me: "Um, okay. Your boss, a C-Level exec, told me to. Not recently, but a while back he was very clear to me that I should delegate tasks like TaskA to Junior's team."
    Boss: "Huh, weird. Yeah, that's not my vision. Sorry about that."
    Me: "No problem. Still, I don't think that excuses Junior. I gave him simple instructions on a simple task, and he made some very basic mistakes."
    Boss: "That's not his role though."
    Me: "I hear that. But he thinks TaskA is his role, and he was willing to take it on. I'm not going to delegate things that are in his role if he can't follow simple instructions."
    Boss: "We're still trying to delineate responsibilities around TaskA. I don't have details, but see TaskA as being within the realm of another team. We just don't have approval to build out that team's headcount."
    Me: "Yeah, I know headcount is an issue. But we can have either limited headcount, or hire inexperienced employees. Either quantity or quality. We can't slack on both. We can't have people who aren't carrying their weight."
    Boss: "Junior shouldn't have to carry TaskA."

    Junior isn't related to anybody, I can guarantee that. I was there when he was hired.

    There are multiple factors at play here, and forest/trees is definitely one of them. We're understaffed in terms of both quantity and quality of employees, and it affects my manager too. The culture of my department is to look for expediency. Perhaps he just didn't want to spend precious mental CPU cycles thinking about this, when there was a convenient excuse to dismiss the problem.

    Alternatively: my manager and I have had many conversations about role responsibilities, and he may have come into this conversation thinking that this was going to be about that, rather than Junior's general professional skills like 'communication' and 'following instructions.'

    Another possibility: there's a reason we're understaffed in both quality and quantity. We don't want to pay for good IT people, full stop. It's hard enough in Seattle where big tech companies siphon talent off from smaller players. We can't compete with Amazon or Microsoft on keeping tech talent. Maybe he doesn't want to spend precious time interviewing replacements for Junior. Maybe he is pessimistic he could get anybody better than Junior in the competitive Seattle market. Both of those are perfectly understandable reasons. I don't think they're good reasons, but I can at least sympathize.

    One thing I like to remind people about where I work is that I negotiated my starting salary to the very maximum of the range they offer for my position. I wanted to work for the company because I like their politics and values. We're explicitly pro-gay, pro-BLM, etc and we've actually done a lot of community action to support those values.

    But they wanted to drastically underpay me and in the interviews I channeled my internal Don Draper and imagined that I had a big swinging dick with "give me the money" tattooed on the girthy shaft

    I got the salary I wanted. But I doubt other people in my department showed half as much hubris. Most of the people in my department are underpaid for their talent - they're smart, hard-working people. I'm pretty happy with the composition of our department right now.

    But once in a while, we get somebody whose talent matches the low pay.

    Depending on internal HR processes for firing people, it might've just been that any work outside the role is completely irrelevant, so manager was getting that Jr is incompetent but can't really acknowledge it in this case.

    Seriously seriously seriously. My ability to negotiate jobs changed drastically when I started interviewing without caring. I know that's a statement from a position of job privelege, so I hope you'll forgive me for it in pursuit of the advice. The best time to interview for jobs is when you don't need one at all, and frankly don't even WANT the job, because you can be as gutsy as you want during the interview. Demand salary info. I realized I could ask for WAY more than I had by doing this and substantially changed my negotiating by just doing fishing interviews.

    What is this I don't even.
