The switch should be configured with a default gateway if the switch will be managed remotely from networks not directly connected. The default gateway is the first Layer 3 device (such as a router) on the same management VLAN network to which the switch connects.
How do you set the default gateway on a switch?
This chapter consists of these sections:
- Understanding How the Switch Management Interfaces Work
- Understanding How Automatic IP Configuration Works
- Preparing to Configure the IP Address and Default Gateway
- Default IP Address and Default Gateway Configuration
- Setting the In-Band (sc0) Interface IP Address
- Setting the Management Ethernet (me1) Interface IP Address
- Configuring Default Gateways
Does a switch always need a default gateway?
The switch only needs a default gateway if it will be doing routing. In your case the 4500 will do the routing and should require a default route. The dhcp server hands the client its ip address along with subnet mask and default route. The rest is handled by the 4500.
Why does a switch need a default gateway?
for management purpose on the switch. And if your management workstation is not in the same subnet as the switch, you need to configure default-gateway on the switch since the switch does not know where the management workstation is and what the next-hop address to reach the management workstation.
How do you fix a default gateway?
The steps are as follows:
- Go to device manager on your PC.
- Then expand the network adapter option by right-clicking on the caption.
- After expanding it, the version of the driver you are currently using will be displayed where you have to select the update driver software option from the contextual menu.
What is gateway address?
The gateway address (or default gateway) is a router interface connected to the local network that sends packets out of the local network. The gateway has a physical and a logical address.
Can a switch send traffic off a VLAN?
Without a default gateway, the switch management address (on VLAN 1 in your case, but it could be on any VLAN configured on the switch) cannot send traffic off its network to another network. Click to see full answer.
Configuring the Switch IP Address and Default Gateway
This chapter describes how to configure the IP address, subnet mask, and default gateway on the Catalyst enterprise LAN switches.
Understanding How the Switch Management Interfaces Work
The Catalyst 4500 series, the Catalyst 2948G, Catalyst 2948G-GE-TX, and the Catalyst 2980G switches have three management interfaces:
Understanding How Automatic IP Configuration Works
These sections describe how the switch can obtain its IP configuration automatically:
Preparing to Configure the IP Address and Default Gateway
Before you configure the switch IP address and default gateway, obtain the following information, as appropriate:
Default IP Address and Default Gateway Configuration
Table 3-2 shows the default IP address and default gateway configuration.
Setting the In-Band (sc0) Interface IP Address
Before you can Telnet to the switch or use Simple Network Management Protocol (SNMP) to manage the switch, you must assign an IP address to either the in-band (sc0) logical interface or the management Ethernet (me1) interface.
Setting the Management Ethernet (me1) Interface IP Address
Before you can Telnet to the switch or use SNMP to manage the switch, you must assign an IP address to either the in-band (sc0) logical interface or the management Ethernet (me1) interface. The me1 interface is present only on the Catalyst 4500 series, Catalyst 2948G, Catalyst 2948G-GE-TX, and Catalyst 2980G switches.
Does the 3750 have IP routing?
whether you are asking about end stations connected to the 3750 or are talking about the 3750 itself. For the end stations the 3750 does not matter (s ince it does appear to not have enabled ip routing) and it is a question of what is configured on the end stations for their default gateway.
Is a 3750 a L2 switch?
If you don't tell your PC's to use the switch as their default gateway, the 3750 will only be a L2 switch, which doesn't require any routing or gateway configuration. What is most likely in your setup is your hosts are pointing to the distribution layer switches for their default gateway, and your 3750 stack is just passing the frames between. ...
Why assign IP address to switch?
Why We Assign IP Address To A Switch ? Answer is very easy : For remote connection ! There are two types of connection that you can connect to a switch which are console and remote. If you don’t have chance to the same location of switch, you need to connect the devices remotely and manage them via SSH or Telnet.
What happens if you don't assign an IP address to a switch?
If you don’t assign an IP address of a switch, it is almost impossible to connect and manage it remotely. So that, network administrators assign an IP address and default gateway to switches.
How do routers decide the best path?
Routers decide the best path via different algorithms according to IP routing protocol that is used for routing. They always check the source and destination IP addresses and make routing using that information.

Configuring Default Gateways
- The supervisor engine sends IP packets that are destined for other IP subnets to the default gateway (typically, a router interface in the same network or subnet as the switch IP address). The switch does not use the IP routing table to forward traffic from connected devices; the switch forwards only IP traffic that is generated by the switch (for ...
