Cisco Switching/Routing :: Set IP Default Next Hop And Cat 3750
Dec 10, 2012I just checked that PBR with setting ip default next-hop is not available on cat 3750. Any other way to do dual-homing ISP without this feature?

Cisco Switching/Routing :: DHCPv6 By Default On 3750?
Apr 7, 2013I gave one of my interfaces a IPv6 address the other day and now all of my servers have IPv6 addresses in that subnet.
I'm reading about "ipv6 nd suppress-ra" and I think that's what I need to disable but that's not a valid command on the 3750.
Is there a way to disable this 'automatic IP giving out' thing that I have going on?
Cisco Switching/Routing :: 3750 - Can't Ping The Default Gateway
May 3, 2012This would probably sound like a stupid question but it took at least 2 hours of my time so far. I have a 3750 switch where a router and a server is connected. From the switch I can ping the router and server with no issue (directely connected). But from the server I am not able to ping the router. The router and the server are in the same subnet. The router is configured as the default router for the server. I am not able to ping the server from the router either. Here's the output of the ip route from the router. The server IP address is 10.1.200.21 and the router IP address is 10.10.200.1
10.0.0.0/8 is variably subnetted, 8 subnets, 3 masks
C 10.1.30.0/24 is directly connected, FastEthernet0/0.30
C 10.1.20.0/24 is directly connected, FastEthernet0/0.20

Cisco Switching/Routing :: 3750 - Default Gateway And IP Redirects?
Apr 10, 2013I have a bit of a mystery on my hands. I had a whole campus of Cisco 3750's cache a new default gateway. Example
Cisco3750#sh ip redirects Default gateway is 10.10.10.1
Host Gateway Last Use Total Uses Interface172.16.0.5 10.10.101.179 0:00 185749 Vlan1172.16.0.76 10.10.101.179 0:01 47254 Vlan1192.168.0.154 10.10.101.179 0:00 183090 Vlan1
My question is what generates a IP Redirect packet or how does the switch know what to change the gateway to? As in my case the changed gateway was a dead IP address. So I am at lose how this happened. I this case the Host IP's are network management servers conducting polling.
Cisco Switching/Routing :: EIGRP Default Route 3750
Jun 20, 2012I have a 3750 at a branch running EIGRP connected to two routers that both have configured:
access-list 1 deny 0.0.0.0
access-list 1 permit any
access-list 2 permit 0.0.0.0
access-list 2 deny any
router eigrp 1distribute-list 1 out FastEthernet0/0distribute-list 2 in FastEthernet0/0
Due to this recently applied config the switch become unreachable from the outside and cannot ping anything. Everything connected to it works fine. I was able to remote into it from a switch behind it and noticed that the 3750 has no default route in the routing table. I do see a default route in the eigrp topology table. How to make the switch learn a default route maintaining the existing configuration on the routers.

Cisco Switching/Routing :: Stacking 3750-X With Universal Image With 3750-G Running BIN Image?

View 9 Replies View RelatedCisco Switching/Routing :: Replacing 3750 24 Port With 3750 48 Port?
May 21, 2012We have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
Cisco Switching/Routing :: Default Routes In Nexus 5k
Apr 29, 2013I have a pair of N5K's, down stream from them are from Fabric Interconnects and a UCS chassis. Upstream is a stack of 3750's then ASA5510's.
I am trying to backup the config to our TFTP server and I am getting 'no route to host'.. I tried to add a route, and found that N5K uses VRF's for routing?? .. After some looking I see there are two base VRF's 'management' and 'default'.. the management VRF has a default gateway entry and a single interface member (mgmt0).. when I look at the default VRF .. there are no interface members or routing entries.. Ok, I can handle that just add some interfaces and add a default gateway. Then I get lost:
I'm able to access the UCS manager..... so how the heck is that even possible if there's no gateway defined anywhere (or maybe I'm missing something?). My theory was: add all other ports but mgmt0 to the default VRF, and have the default gateway point out of the uplinks (a vPC).. but wasn't sure how that would affect anything and mainly just wanted to know how I was able to access the UCS manager in light of the fact that there is no default gateway anywhere that I could see...
Cisco Switching/Routing :: 3750G Won't Factory Default?
Jun 2, 2013I have a 3750G that used to be a Stack Master of a stack comprised of 2 identical switches. Since then, we have removed the stack from production, and I factory defaulted the stack MEMBER and that went fine. I just held the "Mode" button on the front until the lights all lit up and then issued the reload command and the switch came back with no configuration OTHER than the vlan database I issued the "del vlan.dat" command to no avail. I just manually removed all the vlans.
The stack MASTER on the other hand will NOT go back to factory defaults, and will also NOT erase the vlan database. Everything I try will NOT work. I've tried the following
1) Hold mode button & issue a reload after the lights start flashing
2) issue "Write Erase" then issue "reload"
3) issue "Write Erase", then issue "Write", then issue "reload"
4) issue "erase start" then issue "reload" (just in case the "write erase" command is being depriciated or something weird)
5) issue "erase start" then issue "copy run start" then issue "reload"
Is there a special way to reset a StackMaster back to factory defaults?
Cisco Switching/Routing :: Default Gateway And VLAN200

View 1 Replies View RelatedCisco Switching/Routing :: Cat 6509 - How Much Bandwidth For Class-default
Apr 5, 2012I was looking at a problem where a traffic from certain sites have a restricted bandwidth, an ongoing problem for a year or so, apparently this throughput never exceeds around 25Mbps. My customer describes a situation where the end to end utilisation rises, eventually flat-lining at around 25Mbps. how many extra systems come on line, this traffic never exceeds this rate, and end users complain of poor responses.
During my investigation I found that one of the switches (Cat 6509) in the traffic path has a policer configured on a vlan interface, the policer has 3 sections for different traffic based on DSCP markers, and a default (unconfigured) class-default. Various people have had a poke about with this config over the years, with the result that all the traffic has the CoS and DSCP tags set to 0. All this traffic is hitting the class-default in the policer.The link that this traffic hits the Cat 6509 on is a 100Mbps link.
If I was designing this from scratch I'd probably configure a rate for the class-default.my question is, in the case where no specific configuration has been entered for the class-default, how much bandwidth is allocated to this class?
