QOS and BGP
Just got done reading about nested QOS maps and one blurb I read indicated one should be careful not to define a catch all "IP Any Any" ACL for the default class. They sited that the reason was you would then exclude all your routing protocol traffic like BGP and EIGRP, etc. They suggested if... -
3925 and wic 1am
is there anything special I should do to get the 3925 to see the wic 1am installed in slot 0? I put it in there (system was turned off) but after boot, I can't grab that async interface to configure it. It doesn't show up. with T1 wics you have to issue a card type but I've never had to do... -
sanity check on route selection
Sorry, got interupted for a more important 'crisis du jour' which ended up taking much longer than 'du jour'. I should have included extended pings in the first note because I did in fact do them. from the router, if I ping say 137.135.128.255 (yeah, they used that address with an appropriate... -
sanity check on route selection
...is directly connected, FastEthernet0/0 10.0.0.0/16 is subnetted, 1 subnets C 10.8.0.0 is directly connected, FastEthernet0/1 S* 0.0.0.0/0 [1/0] via 10.8.1.1 Now, say you ping the address 137.135.128.209...where would you expect it to go to find that address? Don't ask...this is... -
Enable ssh and disabling telnet
agreed...if bugs don't prevent it from working, the transport command is a better choice. In my original post I only knew it didn't work (not why) and was searching for a work around out of necessity. Part of this may be caused by the fact that so very often I embark on a project only to find... -
Enable ssh and disabling telnet
Okay there's several things here. Fact, the "transport input ssh" did not prohibit telnet however it did allow ssh at the same time as telnet. After much nashing of teeth I found that the problem is a bug in revision 12.2(44)SE5. If I backrev to 12.2(25r) then the command works as documented... -
Enable ssh and disabling telnet
...that I can't apply an extended access list to the line ports. All I need is to block port 23 into vty 0-15. Why is security always an after-thought with these guys? *sigh* sorry for the rant. Everything I want to do on the 3750's isn't supported....I really miss my juniper days sometimes. -
Enable ssh and disabling telnet
I found this post while trying to do a similar thing on my 3750s... transport input ssh does indeed enable ssh to be used. It does not shut off telnet however. After issuing this command I can still use a DOS window and telnet x.x.x.x big as life...and get in! I tried an ACL but that does... -

jitter sla
...part. has simple web server, dns, dhcp and allows ssh just for the switch SLAs to 'hit'. This gives me a unit that, because this is all it does, *should* respond within the same time frame unless there really is some network issue going on. Only thing I can't seem to find is something I... -
switch acts like it rebooted but shows up over 5 weeks!
good call, man. forgot about those pesky things. they were tight but when I went back behind unit the power cord on one switch was barely hanging in there...probably got knocked about by the telco guy who was out last week and doing stuff on teh wall field. thanks! -
switch acts like it rebooted but shows up over 5 weeks!
Anyone ever seen this with 3750 stack? I have 2 3750's in a stack, suddenly they appeared to reboot...traffic frozen, devices unable to respond to the ping tool that monitors them...looked at the stack..all amber lights as you see on a power up. The show ver says the stack has been up over 5... -
fundamental but experience related question on cabling
thanks for the show controller I forgot all about that...mostly I use it on serial ports for my wan links but forgot it could be useful in other situations. It was the gbic, swapped it out problem solved. Not sure why that didn't translate to errors on the port but...stranger things have... -
fundamental but experience related question on cabling
Thanks. The cable runs through a wall, there's no way to patch around. It's isolated so I can't just 'try a different run' as there are none to this area. I can't cut the ends off and re-terminate as it is fiber. The symptoms for the device at the end is excessively long or slow data... -
fundamental but experience related question on cabling
has anyone had cables that were bad but which did not produce physical (as in layer 1 or 2 type errors) on the switch? I know a bad cable can cause retransmissions and such but wouldn't you expect to see errors recorded on the switch if you had a bad cable? I'm about to replace a really hard... -
snmp tsline question
If anyone follows this thread, I learned that the documentation is a bit of a misnomer. the TTY trap is not only from telnet session ended (in fact in this case it clearly was not) but can be generated by ssh sessions that are terminated. We don't have SSH set up on these units so I'm still at... -
Flash
Dude anyone who logs in with the priviledged access can do that. the commands I used in my lab to do this were: rename flash:vlan.dat flash:vlan.dat.renamed then when I created a set of new vlans, I got a new vlan.dat file. I would guess maybe you are looking at a switch that has had other... -
snmp tsline question
every now and again I get a cryptic snmp trap send from an old 4506 switch. I've run through Cisco's mib navigator and as near as I can tell, it's from the TTY trap set. But the trap contents don't tell me squat! When I read up on the TTY trap itself it said that the implication is a TCP... -
ACL to block SNMP traffic to 1 host on same vlan
I am not sure I understand what you are trying to do. But in general if you want to stop a type of traffic on a given vlan, you apply the ACL to the vlan interface like thus: access-list 123 deny udp 10.32.8.8 0 0 0 0 eq snmp any int vlan 11 ip access-group 123 out this would stop snmp... -
two connections setting through Netgear switch
Keep in mind 1.5 MB isn't exactly lightening fast by today's standards. Most DSL lines these days would give minimum 5-6 and some upwards of 8. Also depending on how your provider set this up, they could be reserving portions of that T1 for phone even if you aren't actively using it at that...
